Allonzo has $700
explanation: We need to find 10% or 1/10 of 7000 which is $700. Therefore Allonzo has $700
For this case we have the following system of equations:
Equating the equations:
We look for two numbers that when multiplied, get 16, and when added together, get -8.
These numbers are -4 and -4.
So, the solution is
We look for the value of y:
Finally, the solution is:

Answer:
A: 5x^2 + 42x + 16
B: 12x + 20
C: 351 units
Step-by-step explanation:
A: (5x + 2) * (x + 8) is the same as x(5x + 2) + 8(5x + 2). You just need to solve and simplify that for the area:
x(5x + 2) + 8(5x + 2)
= 5x^2 + 2x + 40x + 16
= 5x^2 + 42x + 16
B: You need to do 2l + 2w, or 2(5x + 2) + 2(x + 8):
2(5x + 2) + 2(x + 8)
= 10x + 4 + 2x + 16
= 12x + 20
C: You can either replace the x in the equation with 5 or replace the x in the figure itself with 5. I will replace the one in the figure with 5 because it is a lot easier:
(5(5) + 2) * (5 + 8)
= 27 x 13
= 351 units
a: 2/38, 1/19, 5.26%
b: 6/38, 3/19, 15.79%
c: 4/38, 2/19, 10.52%
d: 0/38, 0% no chance (all black numbers are odd)
e: 3000/57,000, 3/57, 1/19 or 5.26%
3x + (x-2) =10
4x-2=10
4x=12
x=3
y=3-2=1
Answer is D
