Hello!

You have to find the area of the prism and the pyramid

rectangular prism is lwh

Put in the values you know

15 * 5 * 7 = 525

For a prism you use

$\frac{lwh}{3}$

Put in the values you know

$\frac{15 * 5 *13 }{3}$

Multiply

975/3

Divide

325

Add the values you know

325 + 525 = 850

The answer is D) $850cm^{3}$

Hope this helps!

87-(36.5-11.5)*(-3)+9 simplify using order of operations

OLga [1]

Remember PEMDAS
Do parentheses, results in 25. So whats left is 87-25*(-3)+9
Then you multiply -25 by -3, answer is 75. 87+75+9
Add all of them up. 171
The answer is 171!

What is the length of BC

elena55 [62]

Answer:

BC = 2

Step-by-step explanation:

We first need to use triangle BAD to find BD,

BD is the hypotenuse, so use pythagorean theorem...

(√23)² + (√13)² = (BD)²

23 + 13 = (BD)²

36 = (BD)²

6 = BD

Now BD is the hypotenuse of triangle BCD, so use pythagorean theorem agian to find BC

(4√2)² + (BC)² = 6²

32 + (BC)² = 36

(BC)² = 4

BC = 2
