Distribute -2(x - 3)

4x - 2x + 6 = 10 + -9

Simplify

2x = -5

x = -2.5

4x-2(x-3)=10+(-9)
or, 4x-2x-2(-3)=10-9
or, 2x+6=1
or, 2x=1-6
or, 2x=-5
or, x=-5/2
or, x=-2.5

Answer:

The quadratic equation is : x²+x+1=0

Step-by-step explanation:

Generally:

let S be the sum of the roots z₁ and z₂

and P be the product of the roots z₁ and z₂

then z₁ and z₂ are the solutions for the equation: x² − Sx + P = 0

Now,

S=-1 and P=1 then the equation is x²+x+1=0.

Trent added water to a pool. It took 3 minutes to add 9 gallons of water. How long would it take to add 18 gallons of water to t

Temka [501]

Answer:

6 minutes

Step-by-step explanation:

Set up the proportion as these two fractions equal to each other

9/3 = 18/x

2. Cross multiply so that 9*x=18*3

3. 9x=54, so now you divide 54 by 9

and this will give you

4. x= 6, so it will take 6 minutes to fill

up the 18 gallon pool

Hope this helped!

Have I been solving these equations correctly?

2(-3)² => 2(-3)(-3) => 2*9 = > 18

27+18-11 => 27 + 7 = > 34.

16)

$\bf p(x)=\cfrac{x^2-4}{2x+1}\implies p(-8)=\cfrac{(-8)^2-4}{2(-8)+1}\implies p(-8)=\cfrac{64-4}{-16+1} \\\\\\ p(-8)=\cfrac{60}{-15}\implies p(-8)=-4$

17)

$\bf h(x)=3\cdot 9^x\implies h(-2)=3\cdot 9^{-2}\implies h(-2)=3\cdot \cfrac{1}{9^2} \\\\\\ h(-2)=\cfrac{3}{9^2}\implies h(-2)=\cfrac{3}{81}\implies h(-2)=\cfrac{1}{27}$
