Yes they are if that helps, if you still are unsure than just mesure them and you will see
Answer:
D
Step-by-step explanation:
Factor x^2+2x-8
(x-2)(x+4) = 0
Solve for x
x = 2
x = -4
Answer:
-4v5
Step-by-step explanation:
just a guess
The area of a circle is \pi r^2, where r is the radius of the circle. The diameter of a circle is the length of a line that passes through the center of the circle and stops at the perimeter of circle. The radius of a circle is half the diameter. Divide the diameter by 2 to find the radius.
1. 2.8 m / 2 = 1.4 m
2 .

: Plug in the value we just found for r.
3.

: Use the order of operations (PEMDAS).
4.

The area of the circle is equal to
Answer:

Step-by-step explanation:
I'm going to use the process of elimination to get rid of the equations. The equation for slope is y=mx+b with b being the y-intercept. As you can see the y-intercept in this graph is 4 which removes the third equation as a possible answer. The slope is moving from left to right in a downwards direction which means it is a negative slope. The only answer with a negative slope is b therfore it is your answer.
