C(x) = 5x + 2

This is because at 1 hour it only cost 7 dollars, so it should only have 2 added to the end.

A paperweight is shaped like a triangular pyramid. The base is an equilateral triangle. Find the surface area of the paperweight

stich3 [128]

Answer:

The surface area of the paperweight is $SA=8.3\ in^2$

Step-by-step explanation:

we know that

The surface area of the triangular prism is equal to the area of its triangular base plus the area of its three triangular lateral faces

so

<em>Find the area of its triangular base</em>

$SA=\frac{1}{2}(2)(1.7)$

$SA=1.7\ in^2$

<em>Find the area of its three triangular lateral faces</em>

$SA=3[\frac{1}{2}(2)(2.2)]$

$SA=6.6\ in^2$

Adds the areas

$SA=1.7+6.6$

$SA=8.3\ in^2$

Answer:

1)x is 8.5 y is 1.6 b) y= 7.8 x=6.8

Step-by-step explanation:

1) you have to times 3.4 by 2.5 because if you ties 2 b 2.5 is 5. Then you have to do the opposite for y, you have to divide 4 by 2.5.

b) 10.8 / 2 is 5.4 so 15.6/2 is 7.8. 3.4 * 2 is 6.8

I think its this.

(6 + 5y)3<br> Multiply the algebraic expressions using a Special Product Formula, and simplify.

Kruka [31]

Hello.

The answer is: 15y+18

(6+5y)(3)

=(6+5y)(3)

=(6)(3)+(5y)(3)

=18+15y

=15y+18
