1) In order to solve the equation n/6 = -11.9, you must multiply by 6.

2) $-9m = -45 \\ \\ m = \frac{-45}{-9} \\ \\ m = \frac{45}{9} \\ \\ m = 5 \\ \\ Answer: \fbox {m = 5}$

3) $-14 = \frac{u}{8} \\ \\ -14 \times 8 = u \\ \\ -112 = u \\ \\ u = -112 \\ \\ Answer: \fbox {u = -112}$

4) $-117 = -9h \\ \\ \frac{-117}{-9} = h \\ \\ \frac{117}{9} = h \\ \\ 13 = h \\ \\ h = 13 \\ \\ Answer: \fbox {h = 13}$

5) $\frac{q}{19} = 5 \\ \\ q = 5 \times 19 \\ \\ q = 95 \\ \\ Answer: \fbox {q = 95}$

Find x in this 45°-45°-90° triangle. x = 4.5√2 9 18

postnew [5]

Answer:

x = 9

Step-by-step explanation:

Using the sine ratio in the right triangle and the exact value

sin45° = $\frac{1}{\sqrt{2} }$ , then

sin45° = $\frac{opposite}{hypotenuse}$ = $\frac{x}{9\sqrt{2} }$ = $\frac{1}{\sqrt{2} }$ ( cross- multiply )

x × $\sqrt{2}$ = 9 $\sqrt{2}$ ( divide both sides by $\sqrt{2}$ )

x = 9

One factor of the polynomial 2x^3 - 3x^2 - 3x + 2 is ( x - 2 ). Which expression represents the other factor, or factors, of the

Georgia [21]

Answer:

Option (D)

Step-by-step explanation:

Given polynomial is,

2x³ - 3x² - 3x + 2

If (x - 2) is the factor of the given polynomial,

By synthetic division we can get the other factor.

2 | 2 -3 -3 2

2 1 -1 0

Therefore, other factor of the given polynomial is (2x² + x - 1)

Now (2x² + x - 1) = 2x² + 2x - x - 1

= 2x(x + 1) -1(x + 1)

= (2x - 1)(x + 1)

Therefore, factors of the given polynomial other than (x - 2) are (2x - 1) and (x + 1)

Option (D) will be the answer.
