A. An angle and its supplement equals 180∘ . So subtract 55∘ from 180∘ to get the supplemental angle.
B. The supplement of 170 degrees is 180-170 = 10 degrees. The complement of 55 is 90 - 55.
sorry i don't know the number to C, but i hope i helped a little <3
<u>A
</u><u />You can find the area of a trapezoid with a+b/2*h. If you do so with those numbers, you will get 108.
<u>B
</u><u /><u />If you multiply 2.5 by 108, you can find the cost to tile the entire trapezoid. This is $270 even.
<u>C
</u><u />To solve for the area of a parallelogram, you can simply multiply bh. If you do so with these numbers, you will get 96.
<u>D
</u><u />If you multiply 3 by 96, you can find the cost to tile the entire parallelogram. This is $288 even.<u>

its the only that makes sense
Answer:
Option D: 3x2 + 2x - 1
Step-by-step explanation:
Given that:
=(5x2 - 5x + 3
)- (2x2 +7x- 4)
As we have to subtract them so by simplifying:
"-" sign will alter all signs in the bracket
= 5x2 - 5x + 3 - 2x2 + 7x - 4
Now by adding same terms
= 5x2 - 2x2 - 5x + 7x + 3 -4
= 3x2 + 2x - 1
i hope it will help you!
