MRCORRECT has answered the question
Step-by-step explanation:
Base = b
height =h = b+7
Area = 1/2 * b* h
60 = 1/2*b*(b+7)
120 =b2+7b
b2+7b-120=0
(b+15)(b-8) =0
b=-15 and b=8
base cannot be negative
so base =b =8 cm
The first answer in simplest form is : 6n+10
The second answer in simplest form is: -a/5_20
