Which answer shows this equation written in standard form?

Iteru [2.4K]

So first we solve and simplify
pemdas
first parenthasees

9-4(x-y)=-6x+6
distribute using distributeive property of multiplication which is a(b+c)=(ab)+(ac)

so -4(x-y)=-4x+4y

9-4x+4y=-6x+6
add 6x to both sides
9+2x+4y=6
subtract 9 from both sides
2x+4y=-3
only B matches this
B is the correct answer

(I don't know what standard form is but I know what simplified is)

Find the volume of the following<br> square pyramid. Please help

Neko [114]

Answer:

Volume of square pyramid is 3466.6 cm³

Step-by-step explanation:

We are given:

Base edge of square pyramid = 20 cm

Height of square pyramid = 26 cm

We need to find Volume of square pyramid

The formula used is: $Volume=\frac{1}{3}a^2h$

Where a is base edge and h is height of pyramid

Putting values in formula to find the volume

$Volume=\frac{1}{3}a^2h\\Volume=\frac{1}{3}(20)^2(26)\\Volume=\frac{1}{3}(400)(26)\\Volume=\frac{1}{3}(10400)\\Volume=3466.6 \ cm^3$

So, Volume of square pyramid is 3466.6 cm³
