What is the value of x?

mel-nik [20]

Answer:

x = 24

Step-by-step explanation:

1.) put the equations together and equal them to 180

2.) combine like terms

8x - 12 = 180

3.) divide both sides by 8

8x = 192

4.) simplify

x = 24

Simplify what is written here

Inessa05 [86]

When multiplying terms that have the same base (in this case, $x$ ) but different exponents, you can add their exponents to make them one term.

In this case, we can add the exponents of $x$ :

$x \cdot x^5 \cdot x^5$

$x^{(1 + 5 + 5)}$

$\boxed{x^{11}}$

A simplified version is $x^{11}$ .

Guys help me pls I need it immediately

julsineya [31]

Answer:

Hey there!

First, we want to find the side length of the large triangle.

1/2bh=y cm^2

bh=2y cm^2

Since b and h are the same here, we have b^2= 2y, $b=\sqrt{2y}$ .

And we have FC= $\frac{\sqrt{2y} }{2}$ .

Area of shaded triangle: $\frac{1}{2} (\frac{\sqrt{2y} }{2})(\frac{\sqrt{2y} }{2})$ .

This is equal to: $\frac{1}{2}(\frac{2y}{4})$ , or y/4.

Let me know if this helps :)
