Answer:
D is the answer
Step-by-step explanation:
-15 Is the same as 15 its just negative but they have the same distance.
H = hrs she worked
p = phone calls she answered
h x 10 + p x .25 = maggies earnings
Part A
h x 10 + 60 x .25 = 115
Part B
h x 10 + 15 = 115 (multiplied 60 x .25)
h x10 = 100 (subtracted 15 from each side of the equation)
h = 10 (divided 10 into each side)
Part C
10 hrs

Answer:
Answer is 36cm
Step-by-step explanation:
Given:-
The perimeter of a square is 24 cm
To Find:-
It's Area
Solution:-
One side of the square
=24/4cm
=6cm
We know that, formula of the area of a square,
Area=(one side)^2
so,the area of the square=6^2cm=36
Important formula:-
•Perimeter of square=4×one side
•Perimeter of rectangle =2(length+breadth)
•Area of rectangle=length×breadth
I hope it's helpful!

Answer: C = -4</h3>
==================================================
Work Shown:
C(x+2) - (x+2)(x-2) = 0
(x+2)(C-(x-2)) = 0
(x+2)(C-x+2) = 0
x+2 = 0 or C-x+2 = 0
x = -2 or x = C+2
If we want one solution only, then we must make C+2 = -2 which solves to C = -4
If C = -4, then x = C+2 = -4+2 = -2 which matches with the first solution mentioned. If C is anything else but -4, then we'd have two different solutions (eg: C = 10 leads to x = C+2 = 12 as the other solution)
