Answer:
[tex]x^{3} -x^{2} -5x-3[/tex]
Step-by-step explanation:
you use distributive property for this, or you can do the box method
distributive:
[tex]x(x^{2} +2x+1)-3(x^{2} +2x+1)[/tex] (you multiply the second equation by x-3)
then distribute, or multiply everything
[tex]x^{3} +2x^{2} +x-3x^{2} -6x-3[/tex]
then collect like terms
[tex]x^{3} -x^{2} -5x-3[/tex]

The value of y varies directly with x, and y = -2 when x = -4. Find y when x = 8.
Answers
Answer:
y = 4
Step-by-step explanation:
8 ÷ -4 = -2
so, multiply each side by -2
-2 x -2 = 4
when x = 8, y = 4
Decide whether each equation is true for all, one, or no values of x.
Answers
1) 6x - 4 = -4 + 6x
6x -6x = -4+4
0 = 0
ans - true
2) 4x -6 = 4x + 3
4x-4x = 3+6
0 = 9
Ans - false
3) -2x+4=-3x+4
-2x + 3x = 4 - 4
x = 0
ans - false

Coefficient definition
Answers
Answer:
In mathematics, a coefficient is a factor linked to a monomium. Given a monomium divider, the coefficient is the ratio of the monomium by the divider. Thus the monomium is the product of the coefficient and the divider. The different coefficients will depend on the factorization of the monomium. This is usually next to the letter that accompanies the algebraic fraction. A numeric coefficient is a constant factor of a specific object. For example, in the expression 9x2, the coefficient of x2 is 9. In elemental algebra, numeric coefficients of similar terms are grouped together to simplify algebraic expressions.

The present age of the father and his son is 32 years and 7 years respectively.

Find how many years ago the product of their age was 116.
product of the present age of their
Answers
Answer:
ok so im so confused but like you know i tried and i got this:
X years ago, the father’s age and the son’s age would be (32 - x) and (7 - x) years old.
(32 - x)(7 - x) = 116
(x - 32)(x - 7) = 116
x^2 - 39x + 224 = 116
x^2 - 39x + 108 = 0
(x - 3)(x - 36) = 0
x = 3, 36
But (32 - x) > 0, so x does not equal to 36.
x = 3
3 years ago, the father would be 29 years old, and the son 4 years old.
i know it sounds crazy but i think its wrong lol

what is 12.5% of 40?
Answers
Answer:
5
Step-by-step explanation:
Answer:
5
Step-by-step explanation:
Solution for What is 12.5 percent of 40:
12.5 percent *40 =
(12.5:100)*40 =
(12.5*40):100 =
500:100 = 5
Now we have: 12.5 percent of 40 = 5
Question: What is 12.5 percent of 40?
Percentage solution with steps:
Step 1: Our output value is 40.
Step 2: We represent the unknown value with $x$.
Step 3: From step 1 above,$40=100\%$.
Step 4: Similarly, $x=12.5\%$.
Step 5: This results in a pair of simple equations:
$40=100\%(1)$.
$x=12.5\%(2)$.
Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both
equations have the same unit (%); we have
$\frac{40}{x}=\frac{100\%}{12.5\%}$
Step 7: Again, the reciprocal of both sides gives
$\frac{x}{40}=\frac{12.5}{100}$
$\Rightarrow x=5$
Therefore, $12.5\%$ of $40$ is $5$
Work out the lengths of sides a and b.

Daniella collected 4242 bushels of peas from her garden today. Tomorrow she will send \frac{3}{7} 7 3 of the peas to market. How many bushels will she KEEP?
Answers
Answer: 24
Step-by-step explanation:
Amount of bushels of peas collected = 42
Fraction that'll be sent to market = 3/7
Fraction that'll be kept = 1 - 3/7 = 7/7 - 3/7 = 4/7
The number of bushels that'll be kept will be:
= Fraction that'll be kept × Total number of bushels collected
= 4/7 × 42
= 24
