Zeroes: x = 8, x = -7

Step-by-step explanation:

Find factors of -56 that add to -1.

-8 and 7

The factored form is:

(x - 8)(x + 7)

The zeroes for this polynomial are x = 8 and x = -7

Find the value of x.

Karolina [17]

Answer:

x=21

Step-by-step explanation:

Following the vertical angles, we can assume that the equation that has x and 87 are equal to each other. From then, you set them equal to each other and solve for x.

87=4x+3

84=4x subtract 3 from both sides

21=x divide by 4 to get the x alone on both sides

Which expressions are equivalent to the one below? Check all that apply. 8^x

Dvinal [7]

$\bf a)\qquad \left( \cfrac{32}{4} \right)^x\implies \left( \cfrac{8}{1} \right)^x\implies (8)^x\implies 8^x
\\\\\\
b)\qquad x^4\impliedby \textit{nothing to simplify}
\\\\\\
c)\qquad 8\cdot 8^{x-1}\implies 8^1\cdot 8^{x-1}\impliedby \textit{same base, add the exponents}
\\\\\\
\left. \qquad \right.\left. \qquad \right.8^{1+x-1}\implies 8^x$

$\bf d)\qquad \cfrac{32^x}{4}\implies \cfrac{(2^5)^x}{2^2}\implies (2^5)^x\cdot 2^{-2}\implies 2^{5x}\cdot 2^{-2}\implies 2^{5x-2}
\\\\\\
e)\qquad \cfrac{32^x}{4^x}\implies \left( \cfrac{32}{4} \right)^x\implies \left( \cfrac{8}{1} \right)^x\implies 8^x
\\\\\\
f)\qquad 8\cdot 8^{x+1}\implies 8^1\cdot 8^{x+1}\implies 8^{1+x+1}\implies 8^{x+2}$
