The value of the x of the equation x² + 2x = 24 is negative 6 and 4, then the correct option is C.
What is a factorization?It is the method to separate the polynomial into parts and the parts will be in multiplication. And the value of the polynomial at this point will be zero.
The expression equation is given below.
x² + 2x = 24
x² + 2x – 24 = 0
On factorization, we have
x² + 2x – 24 = 0
x² + 6x – 4x – 24 = 0
(x – 4)(x + 6) = 0
x = –6, 4
The value of x is –6 and 4.

Write a number with a 7 in it that is 1/10 the size of the 7 in the number above.
Answer:
43.7683
Step-by-step explanation:
When multiplying by 10s, the decimal point moves. Since it is a fraction, making it lesser than an actual 10, the decimal point moves one space to the left (instead of right)
437.683
Take away 430 because we don't need it for this step
7.683
10% of 7.683 = 0.7683
add back 43

The additive inverse of a number gives zero. The additive inverse of the complex number -8+3i is 8-3i.
What is additive inverse?The additive inverse of a number is the other number which when added to the initial number gives the output as zero.
As we know about the additive inverse, therefore, we need a number that will return zero when added to the complex number.
The additive inverse of the complex number -8+3i will be,

Mrs. Bailey is knitting a striped blanket for her granddaughter. She made of the blanket pink, of the blanket green, and the rest
of the blanket was white. Which fraction represents the white part of the blanket?
A) 3/4 of the blanket
B) 5/8 of the blanket
C) 1/2 of the blanket
D) 3/8 of the blanket
...
Answer:
D) 3/8 of the blanket
Step-by-step explanation:
Adding up the pink and green parts, then subtracting it from 1 would yield the white area. Finding a common denominator gives: 2/8 + 3/8 which is 5/8. So 5/8 of the blanket is not white meaning that 3/8 of the blanket is white.

A new spiral notebook contains 10 fewer sheets than a new
composition book. The total number of sheets of paper in
2 new spiral notebooks and 5 new composition books is
540. Which system of equations can be used to find s, the
number of sheets of paper in one new spiral, and c, the
number of sheets in one new composition book?
s - c = 10
2s – 5c = 540
c - s = 10
2c + 5s = 540
S + c= 540
2s - 5c = 10
c - s = 10
5c + 2s = 540
multiply quantity of each and add them together to get total of 540
2s + 5c = 540 or 5c + 2s = 540
The difference in pages is 19 so you would subtract: c-s = 10
answer would be
d: c-s = 10

How do you do this??
Answer:
35 units ^2
Step-by-step explanation:
First, draw lines or count how many units are between each point. Don't go diagonal, just up/down or left/right, like from point B to point A.
So I counted 5 units from point B to A, 5 units from C to D, 7 units from A to D, and 7 units from B to C.
Now, you choose two sides - one that goes up/down and one that goes left/right. This is your base and your height.
So you should have 5 and 7. Now, the equation of a rectangle is base times height (b* h) so you multiply 5 and 7 together to get your answer, 35 units ^2

https://brainly.com/question/22560523
Answer:
Sample response: Algebra tiles would not be a good tool to use to factor the trinomial because you would need to drag an x-squared tile, 18 x-tiles, and 80 plus tiles. That is a total of 99 tiles. It would take a lot of time to drag that many tiles on the board and there might not be enough space to hold all of them. You would also need to determine how to arrange all those tiles to make a rectangle. Since 80 is a multiple of 10, you might recognize that 10 and 8 are the factors that add to 18, which would give you the values to use in the X method.

What is the area of a square?
The area of a square of side l is given by the square of l, that is:

In this problem, we have that [tex]l = \frac{1}{10}[/tex], hence the area is given by:
[tex]A = \left(\frac{1}{10}\right)^2 = \frac{1}{100} = 0.01[/tex]
What is the area of a rectangle?The area of a rectangle of length l and width w is given by the multiplication of the measures, that is:
A = lw.
In this problem, we have that the measures are:
[tex]l = \frac{3}{10}, w = \frac{4}{5}[/tex]
Hence:
[tex]A = lw = \frac{3}{10} \times \frac{4}{5} = \frac{12}{50} = \frac{24}{100} = 0.24[/tex]

The Louvre is an art museum in Paris. A glass square base pyramid sits in front of the entrance
to the museum. If the pyramid is 35 meters wide at the base and has a slant height of 27.03
meters, what is the minimum amount of glass needed to construct the pyramid? Find the Lateral
Area
Answer:
lateral area = 1892.1 m²
Step-by-step explanation:
The lateral surface area of the square based pyramid is required.
lateral surface area = 1/2 × perimeter × slant height
we have to find the slant height using Pythagoras theorem
base = 35
height = 27.03
slant height² = 17.5² + 27.03²
slant height² = 1036.8709 + 424.36
slant height² = 1461.2
slant height = √730.61
slant height = 27.0297983714
slant height ≈ 27.03 m
lateral area = 1/2 × perimeter × slant height
lateral area = 1/2 × 35 × 4 × 27.03
lateral area = 3784.200/2
lateral area = 1892.1 m²

The resistance of a wire varies directly with its length and inversely with the square of its diameter. If 100 feet of wire with diameter 0.01 inch has a resistance of 10 ohms, what is the resistance of 140 feet of the same type of wire if its diameter is 0.01 inch
Answer:
14 ohms
Step-by-step explanation:
The resistance varies directly with length, so increasing the length by a factor will increase the resistance by the same factor.
__
The length of the wire increased by a factor of 1.4 from 100 ft to 140 ft. That means the resistance will increase by a factor of 1.4 from 10 ohms to 14 ohms. (The diameter did not change.)
The longer wire will have a resistance of 14 ohms.
