Answer:

Step-by-step explanation:

The Answer will be 90 because Pie is being replaced with 3, so it would be like 2(3)(15) which equals to 90.

But If Pie remains pie the equation would look like (2)(3.14)(15) which would turn out to be 94.2

Answer:

$\large \boxed{69^{\circ}}$

Step-by-step explanation:

Let y = m∠Y.

Then 90 - y = the complement of ∠Y

And 3(90 - y) = three times the complement of ∠Y

And 3(90 - y) + 6 = six more than three times the complement of ∠Y.

$\begin{array}{rcll}y & = & 3(90 - y) + 6 & \\& = & 270 - 3y + 6 & \text{Distribuetd the 3}\\& = & 276 - 3y & \text{Simplified}\\4y &= & 276 & \text{Added 3y to each side}\\y & = & \mathbf{69} & \text{Divided each side by 4}\\\end{array}\\m \angle Y = \large \boxed{\mathbf{69^{\circ}}}$

Explain why the equation (x-4)2-28=8

Alex17521 [72]

Answer:

x=10 or x=-2

Step-by-step explanation:

add 28 to both sides

(x-4)^2=36

sqrt both sides

remember to get positive and negative roots

x-4=+/-6

add 4 to both sides

x=4+/-6

x=4+6 or x=4-6
