Answer:

x^2 -10x+2

Step-by-step explanation:

(3x^2 - 11x - 4) – (x – 2) (2x + 3)

FOIL

(3x^2 - 11x - 4) – (2x^2-4x+3x-6)

Combine like terms

(3x^2 - 11x - 4) – (2x^2 -x-6)

Distribute the minus sign

3x^2 - 11x - 4 – 2x^2 +x+6

Combine like terms

x^2 -10x+2

The sculpture consists of five identical prisms. JD says the surface area of the sculpture is 44 times the surface area of one p
larisa86 [58]
The complete question in the attached figure

we know that
(see the attached figure n 2 to understand the problem)
[the surface area of one prism]=2*[x*x]+2*[x*y]+2*[x*y]----> 2x²+4xy
[the surface area of the sculpture]=2*[5*x*y]+2*[3*x*x]+2*[3*x*y]--> 6x²+16xy

now
<span>JD says the surface area of the sculpture is 4 times the surface area of one prism
</span>[the surface area of the sculpture]=4*(2x²+4xy)---> 8x²+16xy

we compare the value that JD says with the real value
(8x²+16xy) > (6x²+16xy)
the value that JD says is <span>greater in comparison with the real value
</span>This is because <span>JD should also subtract the areas of eight hidden surfaces.

the answer is 
</span>JD should also subtract the areas of eight hidden surfaces<span>

</span>

canoe rental at howie's canoes costs $5 per hour plus an initial deposit of $15. write an expression for how much it costs to re
vagabundo [1.1K]
This solution only needs proper understanding of the word problem and identification of variables.
Let x = number of hours rental of the canoe

It costs $5 per hour for a canoe. However, for every rental of one canoe, there is a deposit of $15 regardless.
The expression is then 5x + 15.

This expression will solve how much it costs in total to rent one canoe for x hours.
