12 x 2/3= a. a being his current age. hope this is correct!
Name the two given polynomials as
f(x) = 19x³ + 44x²y + 17
g(x) = y³ - 11xy² + 2x²y - 13x³
Create the subtraction f(x) - g(x).
f(x)-g(x) = 19x³ + 44x²y + 17 - (y³ - 11xy² + 2x²y - 13x³)
= (19 + 13)x³ + (44 - 2)x²y + 11xy² - y³ + 17
= 32x³ - y³ + 42x²y + 11xy² + 17
Answer: D
Note that answer D has a typo. 11xy² is correct, but 11x²y is not.
Answer:
the answer is B
Step-by-step explanation:
sorry if it wrong
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
x-(3*x^3+8*x^2+5*x-7)=0
Step by step solution :<span>Step 1 :</span><span>Equation at the end of step 1 :</span><span><span> x-((((3•(x3))+23x2)+5x)-7) = 0
</span><span> Step 2 :</span></span><span>Equation at the end of step 2 :</span><span> x - (((3x3 + 23x2) + 5x) - 7) = 0
</span><span>Step 3 :</span><span>Step 4 :</span>Pulling out like terms :
<span> 4.1 </span> Pull out like factors :
<span> -3x3 - 8x2 - 4x + 7</span> =
<span> -1 • (3x3 + 8x2 + 4x - 7)</span>
Checking for a perfect cube :
<span> 4.2 </span> <span> 3x3 + 8x2 + 4x - 7</span> is not a perfect cube
Trying to factor by pulling out :
<span> 4.3 </span> Factoring: <span> 3x3 + 8x2 + 4x - 7</span>
Thoughtfully split the expression at hand into groups, each group having two terms :
Group 1: <span> 3x3 - 7</span>
Group 2: <span> 8x2 + 4x</span>
Pull out from each group separately :
Group 1: <span> (3x3 - 7) • (1)</span>
Group 2: <span> (2x + 1) • (4x)</span>
