Step-by-step explanation:

4 is added to each number

A/q ,

5x+4/6x+4 = 7/8

Now , cross multiply

7/6x + 4) = 8 (5x + 4 )

42x + 28 = 40x + 32

42x - 40x = 32 - 28

2x = 4

x= 4/2

x= 2

answer :

5x = 10

6x = 12

Answer:

78.5 sq feet

Step-by-step explanation:

Diameter = 10 feet

Radius = 5 feet

Area of circle=πr²

                     = π(5)²

                     = 25π

                     = 25 x 3.14

Answer:

B. 143.4 [tex]\text{mi} ^2[/tex]

Step-by-step explanation:

In simple terms, surface area =  adding area of all surfaces

This figure has 6 sides.

Surface area = 2 * area of trapezium + 2* area rectangle + area of bottom rectangle + area top rectangle

Surface area = 2 * ([tex](\frac{a+b}{2}) * h + 2* (l*w) + l*w + l*w[/tex])

= [tex]2 * (\frac{3+6}{2} * 2.6) + 2* (8*3) + 3*8 + 8*6[/tex]

= [tex]2 * 11.7 + 2* 24 + 24 + 48[/tex]

= 143.4 [tex]\text{mi}^{2}[/tex]

Answer:

The remainder is 11.

Step-by-step explanation:

We are given the polynomial:

[tex]f(x) = x^3 + x^2 - 9x + 23[/tex]

And we want to find its remainder when the polynomial is divided by:

[tex]x + 4[/tex]

We can use the Polynomial Remainder Theorem. According to the PRT, if we divide a polynomial P(x) by a binomial in the form (x - a), the remainder will be given by P(a).

In this case, our binomial is (x + 4) or (x - (-4)). Hence, a = -4.

Then the remainder will be f(-4):

[tex]\displaystyle \begin{aligned}f(-4) &= (-4)^3 + (-4)^2 - 9(-4) + 23 \\ &= 11 \end{aligned}[/tex]

In conclusion, the remainder of the operation is 11.

Step-by-step explanation:

hypotenuse = 12

One leg        = 5

other leg =      x            Substitute into a^2 + b^2 = c^2

x ^2 + 5^2 = 12^2

x^2 + 25 = 144              Subtract 25 from both sides

x^2 = 144 - 25              Combine

x^2 = 119                      Take the square root of both sides

x = sqrt(119)

x = 10.91

Answer:

x = 4

Step-by-step explanation:

Start by setting the two expressions equal to each other, since they're the same height.

6 + 15x = 6x + 42

Subtract 6x from both sides

6 + 9x = 42

Subtract 6 from both sides

9x = 36

Divide both sides by 9

x = 4

An equation is formed of two equal expressions. The value of x is 4.

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

Given that the height of Ashton and James are the same height. Also, Ashton's height is represented by (6 + 15x) and James's height is represented by (6x + 42). Therefore, we can write,

Ashton's height = James' height

6 + 15x = 6x + 42

6 + 15x = 6x + 42

15x - 6x = 42 - 6

9x = 36

x = 36/9

x = 4

Hence, the value of x is 4.
