Factor 6p^2 +15p+9????

To factor the trinomial, you can use the ac method where you multiply the first and last terms together (6 and 9) and add up to 15.
In this case ac= 54
2 numbers that multiply to 54 and add up to 15 would be 6 and 9 so place these numbers where the 15 would be:
6p^{2} +9p + 6p+9
Then group terms to simplify:
(6p^{2} +9p)(6p+9)

Simplify any like terms:
3p(2p+3) 3(2p+3)
And group together again:
(3p+3)(2p+3)
You can simplify a 3 out of the first expression one more time to get:
3(p+1)(2p+3)
Which would be the factored form. I hope this helps :)

Actor using the ac method

for
ax²+bx+c when a≠1

multiply a and c  and remember their product
find what 2 numbers multiply to get that product and add to be
split b into those 2 numbers
factor

so

first factor the 3
3(2p²+5p+3)
multiply a and c
2*3=6
wat 2 numbers multiply to get 6 and add to 5
oh ya, 2 and 3

3(2p²+2p+3p+3)
gropu and factor
3((2p²+2p)+(3p+3))
3(2p(p+1)+3(p+1))
3(2p+3)(p+1) is factored

0.4x + 3.9 = 5.78

1. Subtraction property of equality:

Subtract 3.9 from both sides of the equal sign:

0.4x = 1.88

2. division property of equality:

Divide both sides of the equal sign by 0.4:

X = 4.7

(a)  x^{-5}

(b)  3x^{-7}

(c)  $\frac{4}{3}x^4

Solution:

To write each of the given expression in the form ax^n:

(a)  \frac{x^3}{x^8}

Using exponential rule: \frac{a^x}{a^y}=a^{x-y}

$\frac{x^3}{x^8}=x^{3-8}

$\frac{x^3}{x^8}=x^{-5}

(b) \frac{6x}{2x^8}

Divide numerator and denominator by the common factor 2, we get

$\frac{6x}{2x^8}=\frac{3x}{x^8}

Using exponential rule: \frac{a^x}{a^y}=a^{x-y}

      $=3x^{1-8}

$\frac{6x}{2x^8} =3x^{-7}

(c)  \frac{28x^6}{21x^2}

Divide numerator and denominator by the common factor 7, we get

$\frac{28x^6}{21x^2}=\frac{4x^6}{3x^2}

Using exponential rule: \frac{a^x}{a^y}=a^{x-y}

        $=\frac{4}{3}x^{6-2}

$\frac{28x^6}{21x^2}=\frac{4}{3}x^4

Can’t figure out number 3 please help
Deffense [45]

To figure this out, you need to divide 28/8 to get the cost per hinge from Marks hardware

To figure out Steves Supplies cost per hinge you need to divide 38/11

Mark's = 28 / 8 = $3.50

Steve's = 38/11 = 3.45

Steve has the best deal because it cost $3.45 per hinge. The answer is C
