An expression is shown below.
6ab^2 + 9a^2b
Which of the following shows an equivalent expression?
Answer:
C. 3ab ( 2b + 3a )
Step-by-step explanation:
substitution
Hi! I'm happy to help!
To first solve this, Let's see if we can simplify our expressions using the order of operations: our original expression cannot be simplified. The first expression cannot be simplified. The second expression we can multiply the outside by the parenthesis by the inside, same with the third and fourth.
(make sure everything outside of the parenthesis is being multiplied by each part inside of the parenthesis)
9a²b²
9a²b²
3ab(3b+2a)
ab(9b+6a)
b(9ab+6a²)
9ab²+6a²b
3ab(2b+3a)
ab(6b+9a)
b(6ab+9a²)
6ab²+9a²b
3a²b²(2b+3a)
a²b²(6b+9a)
b²(6a²b+9a³)
6a²b³+9a³b²
Now that we have all expressions fully simplified, let's compare to see which one matches.
Our first expression is nowhere close to what our original expression is, 1 is incorrect.
Our second expression is close, but it has the 9 and the 6 flipped, even if we rearrange the expression like this, 6a²b+9ab², it still doesn't match, so 2 is also incorrect.
Our third expression has the correct numbers, variables, placement, and exponents, so 3 is correct.
Our fourth expression has incorrect exponents, the expression made every variable multiplied by ab an extra time, so 4 is incorrect.
In summary, you should pick number 3, because it is equivalent.

round 32,072 to the nearest ten thousands
Answer:
32,072.0000
Step-by-step explanation:
The radius of the earth is about 4,000 miles. A) what is the approximate diameter of the earth? b) what is the approximate distance around the earth at the equator?
A) diameter = radius x 2
Diameter = 4,000 miles x 2 = 8,000 miles
B) distance around the Earth is the circumference.
Circumference = pi x diameter
Circumference = 3.14 x 8,000 = 25,120 miles
Graph the line that passes through the points (-4, -6) and (-2, -7) and
determine the equation of the line.
143153363335
Answer:
y = -1/2x - 8
Step-by-step explanation:
Slope: ( -7 - - 6 )/(-2 - - 4) = (-7+6)/(-2+4) = -1/2
Point : (-4,-6)
y - - 6 = - 1/2(x - - 4)
y+6= - 1/2(x+4)
y+6= - 1/2x - 2
y = - 1/2x -2 -8
y = -1/2x - 8

The midday temperature, in Celsius degrees (°C), on four successive days is 1.5, -2.6, – 3.4 and 0.5. Calculate the mean temperature.
thanks for anyone who helped <3
Answer:
-1 C
Step-by-step explanation:
Mean = Average
To find the mean simply add all the values and then divide that by the number of given values
So first add the 4 values together
1.5 + -2.6 + -3.4 + .5 = -4
Then divide the sum by the number of values ( there are 4 values )
-4 / 4 = -1
The mean temperature is -1

A cell phone tower casts an 80-foot shadow. At the same time, a 6-foot fence
post casts a shadow of 4 feet. What is the height of the tower?
The height of the tower is 120 feet
How to determine the height of the tower?The given parameters can be represented using the following ratio
Ratio = Height : Shadow
So, we have:
Tower : 80 ft = 6 ft : 4 ft
Express as fraction
Tower/80 = 6/4
Multiply both sides by 80
Tower = 120 feet
Hence, the height of the tower is 120 feet

Marley made three full pitchers of lemonade. Eachpitcher holds exactly five cups of liquid. How many ounces of lemonade did Marley make?
Answer:
120 fluid ounces
Step-by-step explanation:
1 cup = 8 fluid oz
Multiply 15 on both sides (since there is 3 pitchers and each is 5 cups, so 3 * 5 = 15 cups in total for all 3 pitchers) and we get 15 cups = 120 fluid oz.
So that's our answer

Answer:
x = 12
Step-by-step explanation:
27 + 3x - 1 = 5x + 2
27 + (3x - 3x) - 1 = (5x - 3x) + 2
27 - 1 = 2x + 2
26 = 2x + 2
(26 - 2) = 2x (+ 2 - 2)
24 = 2x
24/2 = 2x/2
12 = x
x = 12

JT=3x+5--------> (1)
CT=69----------> (2)
CJ=4x+8-------> (3)
Now,
JT=CT-CJ
3x+5 = 69 - (4x+8)
3x+5=69-4x-8
3x+5=61-4x
taking variables to one side.
3x+4x = 61-5
7x = 56
x = 56/7
x=8
put value of x in (1)
JT=3(8) + 5
JT= 24+5
