IceJOKER [234]

Answer:

Step-by-step explanation:

y=2x²-5x-7

y=2x+2

2x²-5x-7=2x+2

2x²-7x-9=0

2x²-9x+2x-9=0

x(2x-9)+1(2x-9)=0

(2 x-9)(x+1)=0

x=9/2 ,-1

y=11 ,0

solutions are (9/2,11),(-1,0)

Darina [25.2K]

Answer: 48 miles

Step-by-step explanation:

From the question, the distance between Franklin City and Williamsville on a map is 3.2 inches and the scale of the map is 1 inch = 15 miles.

The distance between the cities will be to multiply 3.2 by 15 to get the number of miles since 1 inch = 15 miles. This will be:

= 3.2 × 15 miles.

= 48 miles

The distance between Franklin City and Williamsville is 48 miles.

The area of a rectangular glass slab is 80 square centimeters and its perimeter is 36 centimeters. If the length and width of th
netineya [11]

First, you have to find out the values of the length and width.

Let l = length and w = width.

Set up your equation for area: l * w = 80

Set up your equation for perimeter: 2l + 2w = 36

We can use substitution for this problem, so find out the value of l or w. In this case, I will use the first equation to find out the value of l.

(Divide w on both sides) l = 80 / w

Since I know that l = 80 / w, I can substitute it into the second equation.

2l + 2w = 36, and l = 80 / w

= 2 (80/w) + 2w = 36

Simplify the equation.

= 160/w + 2w = 36

Get rid of the w in the denominator by multiplying the entire equation by w.

= ( 160/w + 2w = 36 ) * w

= 160 + 2w^{2} = 36w

= 2 ( w - 8 ) ( w - 10 )

The solutions for width (w) is 8 or 10. Then, you can use both 8 and 10 as your length and width, either or is fine. Multiply by 4 for each of those values and you get 8 x 4 = 32 and 10 x 4 = 40. The new perimeter would be 2(32) + 2(40) =

a. 144 cm

Hope this helped you! Let me know if there are any confusions :)
