Answer:
18
Step-by-step explanation:
2(x - 5) + 4 = 30
2x - 10 + 4 = 30
2x - 6 = 30
2x = 36
x = 18
Answer:
center point: (-4, 2)
radius: 8 units
Step-by-step explanation:
To find the radius of a figure in a coordinate plane, you have to do x-y where x is the starting point and y is the ending point. so in this case:
-4-(-12)
= -4+12
= 8
Answer:
7m(3m^6 - m^4 + 7)
Step-by-step explanation:
This is a factorization question
All we want to do here is to factor out 7m from each term of the polynomial
This becomes;
21m^7 -7m^5 + 49m = 7m (3m^6 - m^4 + 7)
