Answer:

- 4x³ - 33x² + 31x - 3

Step-by-step explanation:

Each term in the second factor is multiplied by each term in the first factor, that is

x²(- 4x + 3) + 9x(- 4x + 3) - 1 (- 4x + 3) ← distribute all 3 parenthesis

= - 4x³ + 3x² - 36x² + 27x + 4x - 3 ← collect like terms

= - 4x³ - 33x² + 31x - 3

Use the quadratic formula to solve the equation if necessary round to the nearest hundredth
densk [106]
-5y^2 + 2y + 2 = 0

y = -2 ± ✓4 - 4*-5*2. /. -10

y = -2 ± ✓44. / -10

y = -1 ± ✓11. / -5

(-1+✓11)/-5. and (-1-✓11)/-5

Use mental math to simplify the expression. (5 + 23) + 65
ohaa [14]
1. (5+23)+65 = (5+65)+23 = 70+23 = 93 (D)
2. -(4x-7) = -4X+7 (C)
3. 2(6X+9) = 12X+18 (B)
4. 5(X-3) = 35
X-3 = 35/5
X-3 = 7
SO X= 7+3 = 10

THEN NO
9 IS NOT A SOLUTION

Marina CMI [18]

Answer:

Basically, exponents represent the number of times you multiply that number by itself. For example, 3² = 9, because you multiply 3 times 3.

<em>Here's</em><em> </em><em>my</em><em> </em><em>working</em><em> </em><em>for</em><em> </em><em>1</em><em>)</em><em> </em><em>You</em><em> </em><em>need</em><em> </em><em>to</em><em> </em><em>find</em><em> </em><em>the</em><em> </em><em>exterior</em><em> </em><em>angle</em><em>,</em><em> </em><em>then</em><em> </em><em>divide</em><em> </em><em>by</em><em> </em><em>360</em><em> </em><em>to</em><em> </em><em>find</em><em> </em><em>the</em><em> </em><em>number</em><em> </em><em>of</em><em> </em><em>sides</em><em>:</em>

<em>Applying</em><em> </em><em>these</em><em> </em><em>steps</em><em> </em><em>:</em><em> </em>

180 (Interior Angles) - 162 = 18 (Exterior angle)

360 ÷ 18 is<em> </em><em>20</em><em> </em><em>sides</em><em> </em>
