Height of the trapezoids = sqrt (17^2 - 8^2) = 15cms
base = 19 cms
(b) area of each trapezoid = 15/2 (35 + 19) = 405 cm^2
Total area painted blue = 2*405 = 810 cm^2
(c) length of the edges of one trapezoid = 35 + 19 + 2(17) = 88 cms
So one piece of sandpaper ( can sand up to 80 cm) will not be enough to sand all of the edges.
Answer: 5.2 mm 7 mm About mm
Step-by-step explanation: There are several ways to determine the missing information in a right triangle. Once you know all the side lengths, you can compute all of the trigonometric functions. Solving the equation and rounding to the nearest tenth gives you .
Answer:
The answer is (-8+3x). :)
Answer:
-2y
Step-by-step explanation:
Let's simplify step-by-step.
x−y−(x+y)
Distribute the Negative Sign:
=x−y+−1(x+y)
=x+−y+−1x+−1y
=x+−y+−x+−y
Combine Like Terms:
=x+−y+−x+−y
=(x+−x)+(−y+−y)
=−2y
