Step-by-step explanation:
a = -2
b = 3
c = 5
<h2>Question:</h2>
= Solution,
= 3 ( - 2 ) × 5 - ( - 2 ) + 2 × 3
here ... ( + ) × ( - ) = ( - )
= - 6 × 5 - ( - 2 ) + 2 × 3
here .... ( - ) × ( - ) = ( + )
= - 6 × 5 + 2 + 2 × 3
= - 30 + 2 + 6
= - 30 + 8
here the ( - ) have greater variable so...
= - 22
hence - 22 is the answer . ....

PART A:
1) plug in values given to you in the area formula: A=b^2--> 788=s^2
2) solve for x: x=28.071
PART B:
1) find he perimeter formula of a square: P=4s s being a side
2) plug in the value you got for part a as s: P=4(28.071) therefore, P=112.285
