Answer:
The answer is -7
Step-by-step explanation:
So 12 x -7 = -84
Easiest if you do this:
12 x -1 = -12
12 x -2 = 24
12 x -3 = 36
and so on and so forth.
keep following those steps and once you make it to 12 x -7, you'll get you're answer
hope this helps:) hope for brainliest.
Number 1, Jamal has 28 CDs, 1/4 are rock, 1/2 are R&B, and 1/4 are jazz. Since one half are R&B, and half of 28 is 14, 14 of the triangle things will be R&B. Since one fourth of the CDs are rock, and one fourth of 28 is 7, seven of the triangles will be rock. And since one fourth are jazz, and, once again, one fourth of 28 is seven, 7 of the triangles will be jazz. Hope this helps a little.
If Lamont withdraws $2,750 monthly, he will be <u>66 years old</u> (after 134.326 months) when the money runs out.
<h3>How is the number of monthly withdrawals calculated?</h3>
We can calculate the number of monthly withdrawals using an online finance calculator.
It determines the number of periods it will take for the investment to be exhausted, given an interest rate of 3.8%.
I/Y (Interest per year) = 3.8%
PV (Present Value) = $300,500
PMT (Periodic Payment) = $-2750
FV (Future Value) = $0
<u>Results</u>:
N = 134.326 months
Years = 11 years (134.326/12)
Age at FV = $0 is 66 years (55 + 11)
Sum of all periodic payments = $-369,397.09 (134.326 x $-2,750)
Total Interest = $68,897.09
Thus, making a monthly withdrawal of $2,750 will exhaust the investment when Lamont turns <u>66</u>.

Answer:
7i
Step-by-step explanation:
Answer:
Length = 6 cm and width = 4 cm.
Step-by-step explanation:
Let the width be x, then the length is x + 2 cm and its area = x(x + 2).
The new width and length are x + 4 and x + 6, and the new area is
(x + 4)(x + 6).
So we have the equation:-
(x + 6)(x + 4) = x(x + 2) + 56
x^2 + 10x + 24 = x^2 + 2x + 56
10x - 2x = 56 - 24
8x = 32
x = 4 cm = width
and length = 4 + 2 = 6 cm
