I need help again, thanks.

Volume of prism = area of base * height
= area of triangle * height
(in this case triangle)
Volume = ( 0.5*13*13)*7
= (84.5)*7
= 591.5
answer is C

What is the solution of the following system?

alexandr402 [8]

<span>4x-y = 15 3x+2y = -8 Multiplying the first equation by two makes for an easy elimination of the y variable. 8x - 2y = 30 3x + 2y = -8 Add vertically. 11x = 22. Divide by 11 on both sides and get x = 2. Plug into an equation. 4(2) - y = 15 8 - y = 15 8 = 15 + y 8 - 15 = y -7 = y. Thus the solution is indeed (2, -7).</span>

Diagram 2 shows a piece of rectangular card in grey colour

Ilya [14]

Solution:

we have given the length of the rectangular card-

$x + 5 \: cm$

and, width-

$7 \: cm$

now, the area of the card will be- length×width.

so, we have-

$(x + 5) \times 7 \: cm^{2} \\ 7x + 35 \: cm^{2}$

we also have given the length of ribbon-

$7 \: cm$

and, width-

$y \: cm$

so, area of the ribbon is-

length×width

$7 \times y \: cm^{2} \\ 7y \: cm^{2}$

now the area of shaded gray region will be-

$7x + 35 - 7y$

Hence, the required expression would the above expression.
