Answer:
94 cm^2
Step-by-step explanation:
The surface area of a rectangular prism can be found using:
A=2(wl+hl+hw)
We know the width is 3, the height is 5, and the length is 4. We can substitute 3 in for w, 5 in for h, and 4 in for l.
A=2((3*4)+(5*4)+(5*3))
Multiply 3 and 4
A=2(12+(5*4)+(5*3))
Multiply 5 and 4
A=2(12+20+(5*3))
Multiply 5 and 3
A=2(12+20+15)
Add 12 and 20 and 15
A=2(47)
Multiply 2 and 47
A=94
So, the the surface area is 94 cm^2
It is 5 1/9 after being simplified

Answer:
c = -9
Step-by-step explanation:
Knowing that -2 is a root, you can do the synthetic division with an unknown value for c. Then solve for the value of c that makes the remainder be zero. See the attachment for the work.
The second attachment shows that (x+2) is a factor of the resulting cubic.
Answer:
Between 7 and 8
Step-by-step explanation:
6^2 = 36
7^2 = 49
8^2 = 64
9^2 = 81
since 61 is between 7^2 and 8^2, √61 is between 7 and 8
