A rectangle with an area of 120 in 2 has a length 8 inches longer than two times its width. What is the width of the rectangle?

nlexa [21]

width = x

length = 2x+8

area = l x w

x<span>(2x+8)</span>=120

<span><span>2<span>x^2</span>+8x−120=0 </span> </span>

<span><span><span>x^2</span>+4−60=0 </span></span>

<span><span><span>(x+10)</span><span>(x−6)</span>=0</span> </span>

<span><span>x=−10 and x=6 </span></span>

<span><span> width has to be a positive number</span></span>

Width = <span>6 </span> inches.

6. Find the missing value. Show your work.

VLD [36.1K]

For the 51-deg angle, y is the opposite leg, and 12 is the hypotenuse.
The trig ratio that relates the opposite leg and the hypotenuse is the sine.

sin A = opp/hyp

sin 51 deg = y/12

y = 12 * sin 51 deg

y = 9.3

Solve the inequality. Graph the solution on a number line. 7 ≥ t/-2

Elodia [21]

$t\geq -14$

The graph is shown in the figure attached.

Step-by-step explanation:

We need to solve the inequality $7\geq \frac{t}{-2}$ and graph the solution.

Solving the inequality: $7\geq \frac{t}{-2}$

Switch sides and reverse the inequality:

$\frac{t}{-2}\leq 7$

Multiplying both sides by -2 and reverse the inequality

$-2\frac{t}{-2}\geq 7*-2$

$t\geq -14$

The graph is shown in the figure attached.
