I really need help on this one
ladessa [460]

Answer:

Step-by-step explanation:

1.Find X

x^2 +8x+15 = (x+5)

       -x             -x

x^2+7x+15=5

            -5  -5

x^2 +7x+10=0

Do the quadralic formula

a=1 b=7 c=10

<u>-7±√7^2-4(1)(10)</u>

          2(1)

<u>-7±√49-40</u>

        2

<u>-7±√9</u>

    2

-7±3

divide 2 by each number

-3.5 ± 1.5

-3.5+1.5           -3.5-1.5

     -2                    -5

x= -2 x=-5

2. find the length of the garden

-2+5 =3

the length is 3

3. plug in the length to the area of the garden

-5^2+8(-5)+15=3

solve

25-40+15=3

0=3

the width of the garden is 3 square feet

Tri City sells four times as many dishwashers as Solly Company. The difference between their sales is 96 dishwashers. How many d
kondaur [170]
We use a system of equations to solve this. Since tri city sells 4 times it becomes 4x and solly company is x. Then we do 4x-x=96. 3x=96. x=32. We are not finished yet. We still have to multiply x by 4. x=128. Tri City sold 128 dishwashers.

I would go with 12.5

I’m more of an English person but that’s my best guess.

3/24
1/8
1 divided by 8
=12.5

Hope you get it right :)

1/4 of Mai’s height is equal to 2/5 of Jon’s height. Find the ratio of Mai’s height to Jon’s height.
nasty-shy [4]

1/4th of Mai’s height is equal to 2/5th of Jon’s height

Let 'x' represent Mai's height and 'y' represent Jon's height.

Therefore, 1/4th of "x" should be equal to 2/5th of "y". This gives us the following equation :

(1/4)x = (2/5)y

multiply both sides by 4/y

x/y = 4*(2/5)

x/y = 8/5

x:y = 8:5

The ratio of Mai's s height to Jon's height is 8 to 5
