a negative times a negative = a positive
so (a * b) + c = 12
(-2 * -3) +6 = 12
6+6 = 12
Ok, so we know that the radius of Sphere A is 24 cm, and we know that the diameter of Sphere B is 42 cm. To find the radius of Sphere B, all we need to do is divide the diameter by two. The radius of Sphere B is 21 cm. 24 times what factor is 21? Well,

is equal to 21. All we need to do now is simplify it. Divide the numerator and denominator by 3, and we get
Answer:
I think 38%
Step-by-step explanation:
The answer is for this question is c
2(3x+2)+2(2x-1)
=10x+2
This is a polynomial
So the answer is c
Ok, so
Length = L
Width = L + 7
Since area = length x width, then
30 = L × (L + 7)
Remember that L + 7 Is width so...
L + 7 = 30/L
So the expression for the width in terms of length would be...
w = 30/L - 7
