Answer:

10.7

Step-by-step explanation:

Let x be the missing side.

The rectangles are similar. Wich means:

● 8/9 = x/12

Cross multiply

● 9x = 8×12

● 9x = 96

Divide both sides by 9

● 9x/9 = 96/9

● x = 10.666

Round it to the nearest unit

● x = 10.7

Say that you are about to make a major purchase and would like to save money on sales tax. Which of these is a viable way to red
mafiozo [28]

Answer: c.) Sales tax varies by state, so you can travel to a state with a lower tax rate and make your purchase there.

Step-by-step explanation:

Sales tax rates vary significantly from state to state, so you can save money if you know what state has a lower sales tax rate, so you can travel to that state and make your purchase there.

There is a list of states with lower sales tax rates:

1. Alaska 1.43% Sales tax rates

2. Hawaii 4.41% Sales tax rates

3. Wyoming 5.36% Sales tax rates

4. Wisconsin 5.44% Sales tax rates

5. Maine 5.50% Sales tax rates

6. Virginia 5.65% Sales tax rates

Use the graphs to estimate both solutions to x^2+x-4=0
Bogdan [553]

Answer:

No graph so we'll use the quadratic formula

x^2+x-4=0

a = 1

b = 1

c = -4

x = -1 +- sqr root (1^2 - 4 * 1 * -4) / 2

x = (-1 +- sqr root (1 +16) ) / 2

x1 = (-1 + sqr root (17)) / 2

x2 = (-1 - sqr root (17)) / 2

What are the real zeros of the function g(x) = x^3 + 2x^2 − x − 2?
PSYCHO15rus [73]
If there are real roots to be found for this polynomial, the Rational Root Theorem and synthetic division are the best way to find them. I teach from a book that uses c and d for the possible roots of the polynomial.  C is our constant, 2, and d is the leading coefficient, 1.  The factors of 2 are +/- 1 and +/-2.  The factors for 1 are +/-1 only.  Meaning, in all, there are 4 possibilities as roots for this polynomial.  But there are only 3 total (because our polynomial is a third degree), so we have to find the first one, at least, from our possibilities above.  Let's try x = -1, factor form (x + 1).  If there is no remainder when we do the synthetic division, then -1 is a root.  Put -1 outside the "box" and the coefficients from the polynomial inside: -1  (1  2  -1  -2).  Bring down the first coefficient of 1 and multiply it by the -1 outside to get -1.  Put that -1 up under the 2 and add to get 1.  Multiply 1 times the -1 to get -1 and put that -1 up under the -1 and add to get -2.  -1 times -2 is 2, and -2 + 2 = 0.  So we have our first root of (x+1).  The numbers we get when we do the addition along the way are the coefficients of our new polynomial, the depressed polynomial (NOT a sad one cuz it hates math, but a new polynomial that is one degree less than that of which we started!).  The new polynomial is x^{2} +x-2=0.  That can also be factored to find the remaining 2 roots.  Use standard factoring to find that the other 2 solutions are (x+2) and (x-1).  Our solutions then are x = -2, -1, 1, choice B from above.
