Please help me it is an easy question

Ugo [173]

Answer:

200 yd²

Step-by-step explanation:

A = 17 yd

B = 15 yd

C = 2 yd

D = 8 yd

b) Area of rectangle = length * width

$\sf Area \ of \ 2 \ triangle = 2* \dfrac{1}{2}* base * height = base* height\\\\$

Area of right triangular prism = Areas of two triangle + area of the upper rectangle + area of middle rectangle + area of below rectangle

= 8 * 15 + 17 * 2 + 15 *2 + 8*2

= 120 + 34 + 30 + 16

= 200 yd²

3y2+5y-(4y2+5)-8y2-(-7-3y2)

Goshia [24]

Answer:

$-6y^2+5y+2$

Step-by-step explanation:

I'm assuming you want to simplify:

$3y^2+5y-(4y^2+5)-8y^2-(-7-3y^2)$

Distribute to get rid of the ( ):

$3y^2+5y-4y^2-5-8y^2+7+3y^2$

Put like terms together:

$3y^2-4y^2-8y^2+3y^2+5y-5+7$

Combine the like terms:

$-6y^2+5y+2$

There are 350 books at most in 2 shelves, how many books at most in 5 shelves?

Flura [38]

If there are 350 in 2 shelves we can estimate that in 4 shelves there are 700. Then 350 divided by two= 175. 700 + 175 = 875 at most in 5 shelves
