Answer:
85 square inches
Step-by-step explanation:
The surface area is the area of all the sides and the bottom
The area of the bottom is
A = s^2 since it is a square
A = 5^2 = 25 in^2
The sides are triangles
A = 1/2 bh where b is the base and h is the height
A = 1/2 ( 5)(6)
A = 15 in^2
We have 4 sides
The area of the 4 sides
4*15 = 60 in^2
Add the area of the side to the bottom
25+60 = 85 in^2
Answer:
i need help with this too
Step-by-step explanation:
lmk if you get the answer
At the bank, Derek made 7 withdrawals, each in the same amount. His brother, John, made 5 withdrawls, each in the same amount.
Let x be the amount of one of Derek's withdrawals
Each of John's withdrawals was $5 more than each withdrawal that Derek made.
x + 5 is t the amount of one of John's withdrawals
Derek made 7 withdrawals
So amount withdraw 7 times = 7x
John made 5 withdrawals
So amount withdraw 5 times = 5(x+5)
Both Derek and John withdrew the same amount of money in the end
(A) 7x = 5(x+5)
(B) Solve for x
7x = 5x + 25
Subtract 5x from both sides
2x = 25
Divide by 2
x = 12.5
(C) check your solution
we plug in 12.5 for x in 7x= 5x + 25
7(12.5) = 5(12.5) + 25
87.5 = 62.5+ 25
87.5 = 87.5
(D) Each brother withdrawal 87.5 dollars
