Answer:

-3 (x-3) (x+1)

Step-by-step explanation:

− 3 x ^2 + 6 x + 9

Factor out -3

-3( x^2 -2x-3)

The terms inside the parentheses can be factored

What 2 numbers multiplies to -3 and adds to -2

-3*1 = -3

-3+1 =-2

Solve for x: 4(x+5)=3(x-2)-2(x+2)

Zina [86]

Answer:

x = -10

Step-by-step explanation:

Solve the equation by simplifying according to PEMDAS. Then use inverse operations to solve.

4(x+5) = 3(x-2) -2(x+2)

4x + 20 = 3x - 6 - 2x - 4

4x + 20 = x - 10

3x = -30

x = -10

Given: y = 3x - 4.<br><br> For what value of x does y equal zero?

Greeley [361]

X = 4/3 because set y=0.
so 0=3x-4. add 4 to both sides so
4=3x. divide both sides by. 3 and you get x=4/3.

15/20 times 1/4 thank me if u like brainly

MaRussiya [10]

Answer: 3/16

Step-by-step explanation: To multiply fractions, first multiply across the numerators and then multiply across the denominators.

$\frac{15}{20}$ × $\frac{1}{4}$ = ?

15 × 1 = 15

20 × 4 = 80

$\frac{15}{20}$ can be reduced by dividing both the numerator and denominator by the Greatest Common Factor which is 5.

15 ÷ 5 = 3

80 ÷ 5 = 16

Therefore, $\frac{15}{20}$ × $\frac{1}{4}$ = $\frac{3}{16}$
