Y = -5/4x + b is the equation that represents a line that is perpendicular to the line 5y-4x=-15
If you want it in standard form, it is 5x+4y=-15
Answer:
A. 5s+2
B. 8s+8
C. 75
D. 27
Step-by-step explanation:
Is difficult to read the exact expressions. If a mistake is present then fix the number and use the same method.
A. The perimeter of the square is all 4 equal sides added together. The length of a side is
. Since there are four sides then:

Adding 1/4+1/4+1/4+1/4=1. This applies here leaving 5s+2 as the answer.
B. The perimeter of the rectangle is all four sides added together. A rectangle has two pairs of equal side so P = 2l+2w.

C. If s=5 then the sum of the two perimeters is:
5s+2+8s+8
5(5)+2+8(5)+8
25+2+40+8
75
D. Subtract the two perimeters by computing s=7:
8s+8 -(5s+2)
8s+8-5s-2
8(7)+8-5(7)-2
56+8-35-2
64-35-2
29-2
27

=

Multiply both sides by 12, so that we get rid of the fraction in x.
12 · (x+3)/12 = 2/7 · 12
Simplify.
x + 3 = 24/7
Then, subtract 3 from both sides, so that "x" gets isolated.
x = 24/7 - 3
Turn "3" into an improper fraction so that we could find the value of x easier.
3 = 21/3
So :
x = 24/7 - 21/7
Simplify.
x = 3/7
