Answer:
The value of the equation for x is 
or 559.5.
Step-by-step explanation:
Consider the provided equation.
We need to solve the equation for x.
Use the distributive property: 
Add the like terms.
Isolate the variable as shown:
Hence, the value of the equation for x is or 559.5.
Answer:
see below
Step-by-step explanation:
8(n + 2)(n + 4) = 1,144
FOIL
8(n^2 +2n+4n+8) = 1144
Divide each side by 8
8/8(n^2 +2n+4n+8) = 1144/8
(n^2 +2n+4n+8) = 143
Combine like terms
n^2 +6n+8 = 143
Subtract 143 from each side
n^2 +6n+8 -143= 0
Combine like terms
n^2 +6n -135 =0
Factor
What two terms multiply to -135 and add to 6
-9*15 =-135
-9+15 = 6
(n-9) (n+15) =0
Using the zero product property
n-9 =0 n+15=0
n = 9 n=-15
The length cannot be negative so n = -15 cannot be a solution
n =9
Answer:
selling price is $26.4
Step-by-step explanation:
Here, we want to apply the markup percentage so as to get the price of the jewelry
mathematically, we have the selling price as;
$22 + (30% of $22)
= $22 + 4.4
= $26.4
Answer:
18
Step-by-step explanation:
AB = AW + WB
But AW also equals WB because of the bisecting point
x + 6 = 3x
6 = 2x
x = 3
AW = 3 + 6 = 9
WB = 3(3) = 9
9 + 9 = 18°

7y^2 + 10y + 3
7y^2 + 7y + 3y + 3
(7y^2+7y) + (3y+3)
7y(y+1) + 3(y+1)
(7y+3)(y+1)
So the final answer is <span>(7y+3)(y+1)</span>
