Answer:
11
Step-by-step explanation:
42 + 39= 81 and you need to get to 180 so the 3rd angle would be 99 so 99 dived by 9 is 11 so x=11
Answer:
=−30x−62
Step-by-step explanation:
Distribute:
=−3+(−3)(2x)+(−3)(7)+(−4)(6x)+(−4)(7)+−10
=−3+−6x+−21+−24x+−28+−10
Combine Like Terms:
=−3+−6x+−21+−24x+−28+−10
=(−6x+−24x)+(−3+−21+−28+−10)
=−30x+−62
Answer:
=−30x−62 i think :)
Answer:
the formula of a trapezoid is
H(a+b/2)
A= side 1 (usually the two parallel sides, choose one)
b= side 2 (same thing as A but the second line)
The h is height
So we fot 10 and 9
10+9=19
19/2=9.5
9.5*6
57
the Area is 57
Also you drew it wrong (look at image)
