Answer:
105 sq cm
Step-by-step explanation:
The bottom rectangle is 6 x 15 = 90 sq cm
The triangle at the top has a length of 15 - 9 = 6 cm and a height of 11 - 6 = 5 cm.
A triangle is 1/2bh so 1/2 x 6 x 5 = 15 sq cm
Add the areas together

I think you forgot part of the question
Step-by-step explanation:
Answer:
20 inches x 26 inches
Step-by-step explanation:
set up an equation: (2x)(x+7)=520
now just solve it
2x^2+14x=520
x^2+7x-260 = 0
factor: (x-13)(x+20)
x = 13 and -20
13 is the only one that works because you can't have a negative side length
13+7=20
13*2=26
lmk if you don't understand how to solve that equation
40/8=5
$5= 1gal.
5x10=50
So 10 gallons of gas costs $50
Answer:
