Answer:
Yes. x = 30 is a solution for 120 = 4x
Step-by-step explanation:
If x is 30 you substitute the X next to the four for 30 that means you multiply 30 x 4 and you get 120 so X does equal 30
Okay so here's what you do. The arrows mean the the sides are the same length so the > line is 20in. And then they cut this up into 2 triangles and a trapezoid. BUT If you look closely 1 of the Triangles and the Trapizoid make a Parallelogram. The formula for finding the area of a Paralellogram is just b*h. So then you just need to find the area of the other triangle which would be 8*20/2 (the formula is b*h/2 for triangles) and then you add those to answers together. (So it's 20*16+8*20)
The area of Erin's circle to the nearest hundredth is 50.24 in².
<h3>What is the area of the circle?
</h3>
A circle is a bounded figure which points from its center to its circumference is equidistant.
Area of a circle = πr²
Where :
3.14 X 4²
(3.14) (4) (4) = 50.24 in²
