Step-by-step explanation:
3x x 10 = 22
3x x 10 - 10 = 22 - 10
3x = 12
3x ÷ 3 = 12 ÷ 3
x = 4
5x + 8
5(4) + 8
20 + 8
28
Nope! If they were proportional, one would be able to be reduced to the other.
It's like the (however clichéd) example of pie slices! If you cut two pies into 8 and 20 pieces, three pieces of the pie sliced into eight pieces will not be the same as seven pieces of the pie sliced into twenty!
Answer:
Step-by-step explanation:
Hello!
10*17 = > 170 cm²
(3,14 * 8)/4 =>6,28cm²
170 + 6,28 => 176,28cm²
U wouldn’t have a answer because it would be ( 0=0 )
Remember that the degree measure of each exterior angle of a polygon can be found through the formula

where
is the number of sides on the polygon.
Since a pentagon has five sides, the degree measures of each of its five sides would be:

Thus, our answer is Choice B, or 72 degrees.
