Since perimeter means all around it just means adding all the sides. Because you are given length and width your equation would then be, " (5)+(5)+(2x=14)+(2x+14). Now since area means length times width you would multiply length times width. Since x=7 you would multiply 7x5 and the area equals 35. Questions 35-37 are indeed correct. You're smart ! By the way I'm twelve so hopefully you found this helpful.

A rectangular prism has a dimension x units ,2x units and x+8 units . Which expression represents the surface area of the prism
Alekssandra [29.7K]

Formula to find the surface area of the rectangular prism is:

2wl + 2lh + 2hw,

where w is width, l is the length, and h is height of the prism.

Given, the dimension x units ,2x units and x+8 units .

So, we can plug in w= x, l= 2x and h= x+8 in the above formula to get the expression for the surface area of the prism. Hence,

Surface area= 2wl + 2lh + 2hw

=2*x*2x+ 2*2x*(x+8)+2*(x+8)*x

= 4x²+4x(x+8)+2x(x+8) (By multiplying)

= 4x²+4x²+32x+2x²+16x (Multiplying by distribution)

=(4x²+4x²+2x²)+(32x+16x ) (Making the groups of like terms)

= 10x²+48x (Adding the like terms)

So, the expression 10x²+48x units² represents the surface area of the given prism.

raketka [301]
Jessica is buying several Bunches of Bananas
Find which set of banana offers is best buy
=> 10 pounds of bananas for 14.90 dollars
to get the answer, divide 14.90 by 10
=> 14.90 / 10
=> 1.49, thus, in every pound of bananas, the price is 1.49 dollars
Second Offer
=> 8 pounds of bananas for 12.08 dollars
=> 12.08 / 8
=> 1.51 dollars = the price of banana per 1 pound.

Thus, the best buy of banana offer is the 10 pounds for 14.90 dollars.
