Answer:
<h2>A. x = -1 or x = 3</h2><h2>B. first</h2>
Step-by-step explanation:

Step-by-step explanation:
y is the hypotenuse.
to find the hypotenuse:
a² + b² = c²
c = √ ( a² + b² )
y is the hypotenuse, a = 3, b = 3
y = √( a² + b² )
y = √ ( 3² + 3² )

Answer:
15pi/60 = pi/4 hopefully this helps :)
Step-by-step explanation:
Angle in radians = arc / radius
15pi/60 = pi/4
Answer:
2(L+W)H
Step-by-step explanation:
- <em>The lateral surface area of a prism is the total of the area of the faces.</em>
- <em>The lateral area of the prism is equal to the perimeter of the base times the altitude.</em>
Surface area= 2(L+W)H
Answer:
a =9
b= 28
Step-by-step explanation:
The parts of the ratio must be equal
5:7:a = 20:b:36
How do we get from 5 to 20
We multiply by 4
So multiply the first by 4
5*4:7*4:a*4 = 20:b:36
Ratio 1
5*4 =20 true
Ratio 2
7*4 =b
28 = b
Ratio 3
4a = 36
Divide by 4
4a/4 = 36/4
a = 9
