Y= 2x + 1 is the equation hope this helps!
Answer:
kate will be 44 years old
Step-by-step explanation:
12 + 10 = 22 x 2 = 44
Pair up the terms into separate groups. Then factor each group individually (pull out the GCF). Once that is finished, you factor out the overall GCF to complete the full factorization.
8r^3 - 64r^2 + r - 8
(8r^3 - 64r^2) + (r - 8)
8r^2(r - 8) + (r - 8)
8r^2(r - 8) + 1(r - 8)
(8r^2 + 1)(r - 8)
So the final answer is (8r^2 + 1)(r - 8)

Edit:
Problem 1b) Follow the same basic steps as in part A
28v^3 + 16v^2 - 21v - 12
(28v^3 + 16v^2) + (-21v - 12)
4v^2(7v + 4) + (-21v - 12)
4v^2(7v + 4) - 3(7v + 4)
(4v^2 - 3)(7v + 4)
The answer to part B is (4v^2 - 3)(7v + 4)

Second Edit:
I apologize for the first edit. I misread what you were asking initially. Here is problem 2A. We follow the same basic steps as in 1a) and 1b). You'll need to rearrange terms first
27mz - 12nc + 9mc - 36nz
27mz + 9mc - 12nc - 36nz
(27mz + 9mc) + (-12nc - 36nz)
9m(3z + c) + (-12nc - 36nz)
9m(3z + c) -12n(c + 3z)
9m(3z + c) -12n(3z + c)
(9m - 12n)(3z + c)
3(3m - 4n)(3z + c)
X² × x = x³
x² × 1 = x²
1 × x = x
1 × 1 = 1
x³ + x² + x +1
The answer is a
To divide fractions, you would multiply the reciprocal. What this means is that you would flip the fraction, so if you flip the fraction 35/48, that is 48/35. And because we flipped it, we now need to multiply it with the other fraction. This would be
. Now we can use cross multiplication to simplify. We can see that 48/24 is 2, and 2/1 = 2. So we can replace 48 with 2, and 24 with 1. Now we can also see that 35/7 = 5, and 5/1 = 5. So we can replace 35 with 5 and 7 with 1. So our new fractions are
. And therefore your answer is D. 2/5. Hope this helps. Feel free to ask more questions, or ask questions about my explanation.
