Answer:
(x + 3)(3x - 4)
Step-by-step explanation:
Given
3x² + 5x - 12
Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term.
product = 3 × - 12 = - 36 and sum = + 5
The factors are + 9 and - 4
Use these factors to split the x- term
3x² + 9x - 4x - 12 ( factor first/second and third/fourth terms )
= 3x(x + 3) - 4(x + 3) ← factor out (x + 3) from each term
= (x + 3)(3x - 4)
Thus
3x² + 5x - 12 = (x + 3)(3x - 4) ← in factored form
Answer:
2x + 3y +1
Step-by-step explanation:
-2x + 4x -6y + 9y +3 -2 (arranging)
2x + 3y + 1
The new price would be $19.99
29.99 x .6666 = $19.99
(Old price multiplied by discount percentage = new price)
Answer:
The required equation is
4p = 2.24
And p = 0.56 [ where p is in $]
Step-by-step explanation:
Given that Selena buys 4 peaches that weight 1 pound in all.
Peaches are on sale for $2.24 per pound.
Since the total weight of peaches is 1 pound.
So the price of 4 peaches is $2.24.
Let p be the price of 1 peaches.
Then the price of 4 peaches is $(4×p)
= $4p
According to the problem,
4p = 2.24
⇒p=0.56 [ where p is in $]
The required equation is
4p = 2.24
And p = 0.56 [ where p is in $]
let x x +2 x+4 three consecutive odd <span>integers
