F(-5) = -5^2 - 2*(-5) - 7 = 25 - (-10) - 7 = 25 + 10 - 7 = 25 + 3 = 28
Answer:
The radius is given its 10 in
The diameter is 20 in
Step-by-step explanation:
Two find the diameter given the radius you just multiply by 2
10x2=20 therefore the diameter is 20
Hope this helps :)
Answer
D. 3m - 4/3 -2/m
<u>Explanation</u>
(9m²-4m-6) ÷ 3m = 9m²/3m - 4m/3m - 6/3m
Carry out the division, each term is divided by 3m.
9m²/3m = 3m
- 4m/3m = -4/3
- 6/3m = - 2/m
Finally you will get,
<em>3m - 4/3 -2/m</em>

Answer:
x = 12
Step-by-step explanation:
Here, we want to find the value of x
To do this, we use one of the circle tangent relationships
we have this as:
8^2= 4(4 +x)
8^2 = 16 + 4x
64 = 16 + 4x
64-16 = 4x
4x = 48
x = 48/4
x = 12
