Lydia created a rectangle shape design that is 12 inches wide and 15 inches long she plans to make an enlargement of the design that will be similar to the original design. The enlargement will be 80 inches wide. how long will the enlargement of the design be?

1200 inches long.

Step-by-step explanation:

the enlargement went from 1 inches wide to 80 inches wide.So which means it was being multiply by 80.

so you have to multiply 15 by 80 to find length of the enlargement or how long the enlargement of the design will be.

15 * 80=1200

answer: its the third option.

step-by-step explanation:

i just took the test.

5x + 3y = - 4

step-by-step explanation:

the equation of a line in standard form is

ax + by = c ( a is a positive integer and b, c are integers )

express the line first of all in slope- intercept form

y = mx + c ( m is the slope and c the y-intercept )

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (7, - 3) and (x₂, y₂ ) = (4, - 8)

m = = -

y = - x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (4, - 8 ), then

- 8 = - + c ⇒ c = -

y = - x - ← in slope-intercept form

multiply all terms by 3 to eliminate the fractions

3y = - 5x - 4 ( add 5x to both sides )

5x + 3y = - 4 ← in standard form
