Answer:
Just remember to divide the diameter by two to get the radius. If you were asked to find the radius instead of the diameter, you would simply divide 7 feet by 2 because the radius is one-half the measure of the diameter. The radius of the circle is 3.5 feet.
Step-by-step explanation:
Answer:
(X+8)(x-10
Step-by-step explanation:
The middle number is -2 and the last number is -80.
Factoring means we want something like
(x+_)(x+_)
Which numbers go in the blanks?
We need two numbers that...
Add together to get -2
Multiply together to get -80Try 8 and -10:
8+-10 = -2
8*-10 = -80
Fill in the blanks in
(x+_)(x+_)
with 8 and -10 to get...
(x+8)(x-10)
5+x=-9
Use the subtractive property of equality to isolate x.
5+x=-9
-5 -5
x=-14
The value that satisfies x is -14. You can check your work by substituting x as -14 and checking if the equation is satisfied.
5+x=-9
x=-14
5+(-14)=-9
5-14=-9
-9=-9
the answer is correct. Succinctly, x=-14.
