r=7
Area of circle =7^2pi=49pim^2
Answer:
Step-by-step explanation:
-5f=-3(8-f)
Opening bracket
-5f = - 24 + 3f
Collecting like terms
-5f - 3f = -24
-8f = -24
Dividing by -8
f = -24/-8
f = 3
To simplify the expression we are going to use the distributive property of multiplication:

.
We can infer from our problem that

,

, and

. So lets apply the property to simplify our expression:

We can conclude that the correct answer is <span>
-8x3 + 6x2</span>
Answer:
2
Step-by-step explanation:
21 divided by 7 is 3 and 14 divided by 7 is 2
we know its 7 because both 14 and 21 can be divided by 7
