Answer:
The formula for the area of a square with sides of length x is A = x2 so
x2 = 400 is the equation
This equation has 2 solutions, namely x = ±√400 = +20 or -20
The negative solution does not make sense because a length cannot be less than 0.
The total length needed to go around the painting is the perimeter of the square, which is
P = 4*x = 4*20 = 80 inches
Answer:
It doesn't have a solution because if you try to graph each line y=5x+10 and y=5x-8, you will have a parallel line
Step-by-step explanation:
<em>line </em>DAC = 180°
180 - 98 = 82°
∠BAC = 82°
A triangle = 180°
180 - 82 - 32 = x
Simplify:
x = 180 - (82 + 32)
x = 180 - 114
x = 66
66°, or C is your answer

Answer:
Total framed print = 517
Step-by-step explanation:
Framed print:
Small = 23
Medium = 264
Large = 188
Extra large = 42
Total framed print = Small + Medium + Large + extra large
= 23 + 264 + 188 + 42
= 517
Total framed print = 517
Unframed print:
Small = 152
Medium = 544
Large = 496
Extra large = 81
Total unframed print= Small + Medium + Large + extra large
= 152 + 544 + 496 + 81
= 1,273
