Answer:
-500/11
Step-by-step explanation:
0.22 in fraction is 11/50
After replacing the decimal with a fraction, subtract it from -10.
You'll have -10÷(11/50)
You'll then change the division sign to a multiplication sign.
You'll then have that -10 × 50/11
-10×50 = -500/11.
5(2x-8)+15=-15 -15 in both sides
5(2x-8)=-30 /5
2x-8=-6 +8
2x=2 /2
x=1

Instead of negative positive and instead of positive negative hope you get it right. Am not that smart
A polynomial with a degree of 3 is understood to have three zeroes or roots. In the given problem in 1, x3 + 6 x2 – 9x – 54, the roots of the polynomial using the calculator are B. B. 3, -3, -6. The same applies for number 2 given the polynomial x3 – 4x2 + 3x – 12. The answer in 2 is D. 4 years. The roots of the polynomial in 3 are:
<span>x1=−0.45117</span>
<span><span>x2</span>=1.77474</span>
<span><span>x3</span>=0.03821+0.70576∗i</span>
<span><span><span>x4</span>=0.03821−0.70576∗i. Hence there is A. 1 negative root.</span></span>
Answer:
12. a = 2
13. 
Step-by-step explanation:
12.
6a(a + 3) = 2a(3a + 5) + 16
First, distribute 6a on the left side, and distribute 2a on the right side.
6a² + 18a = 6a² + 10a + 16
Subtract 6a² from both sides.
18a = 10a + 16
Subtract 10a from both sides.
8a = 16
Divide both sides by 8.
a = 2
13.

The LCD of 2 and 3 is 6. We multiply both sides of the equation by 6 to get rid of all denominators.



Combine like terms on the left side. Distribute the 2 on the right side.

Subtract 2x from both sides.

Divide both sides by 3.
