Answer:
197in^2
Step-by-step explanation:
5x5=25(top face)
5x5=25(left face)
9x5=45(bottom face)
6.4x5=26(right face)
Front and behind face: trapezoid area (trapezoid formula h x (a+b)/2)
(5+9)/2 x 5=7x5=35
35+35+25+25+45+25=197in^2
Step-by-step explanation:
(2ab-7a-4) - (7ab-4)
= 2ab - 7a - 4 - 7ab +4
(-) × (-) = (+)
(-) × (-) = (+)-(-4)= +4
then 4 will be cancelled
= 2ab - 7ab - 7a
= -5ab -7a
