The rectangle has sides of length 5, 9, 5, and 9, so has a perimeter of ...
5 +9 +5 +9 = 28 . . . . units
The perimeter is 28 units.
Answer:
18 and 9
Step-by-step explanation:
The numbers are x and 1/2x.
x + 1/2x = 27
3/2x = 27
x = 18 so the numbers of 18 and 9.
Answer:
38°
Step-by-step explanation:
The measure of angle NPM is 38°.
Isolate the x. Note the equal sign. What you do to one side, you do to the other.
Cross multiply
(4/9)(9)(36) = (x/36)(36)(9)
(4)(36) = (x)(9)
Simplify
144 = 9x
Isolate the x. Divide 9 from both sides
144/9 = 9x/9
x = 144/9
x = 16
16 is your answer
