How do i sovle -8(x-7)=-8(1+3x)

1 answer:

7 0

First, simplify the equation by distributing and combining like terms:

-8x + 56 = -8 - 24x

-8x + (24x) + 56 = -8 - 24x + (24x)

16x + 56 = -8

16x + 56 - (56) = -8 - (56)

16x = -64

16x/(16) = -64/(16)

x = -4

so,

7! = 7×6×5×4×3×2×1

now all you need is a calculator.

Answer:

4 $x^{2}$ -16x+8

Step-by-step explanation:

4(x - 2)(x - 2) - 8 = 4( $x^{2}$ - 4x + 4) - 8 = 4 $x^{2}$ - 16x + 16 - 8 = 4 $x^{2}$ - 16x + 8.

The triangles are similar. Find the value of the variable.

Vitek1552 [10]

Answer:

y = 27

Step-by-step explanation:

The given are two similar triangles.

We can use the following equation to find the variables:

$\frac{y-3}{32} = \frac{18}{24}$

Cross multiply fractions

32*18 = 24(y-3)

576 = 24y - 72

add 72 to both sides

648 = 24y

divide both sides by 24

27 = y
