Answer:
The answer to your question is below
Step-by-step explanation:
Equation 4x - 2y = 8 solve for y
First, pass 4x to the right side -2y = -4x + 8
Pass -2 to the right side y = -4/-2 x + 8 /-2
Simplify y = 2x -4 or y = -4 + 2x
I can not see clearly the work of Charlize and Camille, but the one that has the answer shown above is correct.
To find the perimeter of the square, you add all four sides together:
10x + 10x + (6x + 8) + (6x + 8)
20x + 12x + 16 = P
32x + 16 = P
you have to find x to get the actual perimeter. Since the shape is a square, all 4 sides are equal, so you can set 10x and (6x + 8) as equal to each other.
10x = 6x + 8
4x = 8
x = 2
Now you just plug in x and finish the rest of the problem, and you have the answer:
32(2) + 16 = P
64 + 16 = P
P = 80

Answer:
96
lower right
Step-by-step explanation:
Part 1
Givens
a1 = - 20
d = +4
n = 30
Equation
a30 = a1 + (n - 1)d
Solution
a30 = -20 + (30 - 1)*4
a30 = -20 + 29*4
a30 = - 20 + 116
a30 = 96
=====================
Part 2
Formula
Sum = (a1 + L)*n/2
n = 30
So only the two on the right can be considered
a1 = -20
L = 96
Sum = (-20 + 96)30/2 is the bottom right. D if you think of it that way.
E = 2 + 1/4 n
n = 40
E = 2 + 1/4(40)
E= 2 + 10
E = 12
