Answer:
35
Step-by-step explanation:
5(5)+8-(-2)=25+8+2=35
An artist wants to frame a square painting with an area of 400 square inches.
(a) x is the length of one side of the painting
Area of the square formula is
side is x. so area becomes
We know Area is 400. so the equation becomes
(b) Solve the equation for x
(take square root on both sides)
When we take square root we put +-
+-20 = x
x = +20 in and x=-20in
So there are two solutions for the above equation.
(c)No. we know x is length of the side. the length cannot be negative .
So x=-20 inch is not valid
x=20 inches is our only solution.
(d)To find the length of the wood trim needed to go around the painting, we find the perimeter of the square
Perimeter = 4* side
= 4* x = 4* 20 = 80 inches
Answer:
1 hour 54 minutes
Step-by-step explanation:
1 hour and 9 minutes + 45 minutes gives your answer. However, since 45+9=54, this is convenient, since now we don't need to carry. Thus, 1 hour and 54 min is your answer.
Hope this helps!
Let the angle be x.
Hence, its complement is 90 - x.
x = 3* (90 - x) - 70 = 270 - 3x - 70 = 200 - 3x
4x = 200
x = 50
Thus, the angle is 50°.
The answer is A. > because -3 + 7 is -4 and -10 -2 is -12. -4 is greater than -12. good luck!
