8 0

Answer:

The first question is (n*8) - 4

The second question is no.

Step-by-step explanation:

The first question, you add 8. The first is 1. 1 * 8 = 8 - 4 = 4.

Therefore, the equation is (n*8) - 4

The second question, you can plug in numbers. You can solve for a term. -100 + 17 = -83. -83 is not a multiple of -4. -100 is not a term.

You want to wrap a gift shaped like the regular triangular prism shown. How many

kotegsom [21]

Answer:

$697.6 \ in^2$

Step-by-step explanation:

-Given the dimensions of the box is 8.7 in, 14 in and 10 in.

Let length=14 in, width=10 in and height =8.7 in

#The surface area of a rectangular prism is calculated as:

$Surface \ Area=2(wl+hl+hw)\\\\l=length, w=width, h=height\\\\\therefore Surface \ Area=2(14\times 10+10\times 8.7+14\times 8.7)\\\\=697.6 \ in^2$

Hence, the wrapping paper needed has an area of $697.6 \ in^2$

Simplify the expression: y9 * y-2

agasfer [191]

Answer:

$y^7$

Step-by-step explanation:

If we want to simplify the expression $y^9 \cdot y^{-2}$ , we have to note that exponent rules state that $x^a \cdot x^b = x^{a+b}$ .

This means that if we add the exponents, that will be what we raise y to the power of.

$9 + -2 = 9-2 = 7$

So $y^7$ .

Hope this helped!
