Asail is in the form of a right triangle that is two times as high as it is wide. the sail is made from 4 square meters of material. what is its

4 m

We know that a triangle has half the area of a rectangle of the same height and width. That is, the rectangle that is as high and wide as the sail will have an area of 8 m². Of course, the area of a rectangle is the product of its length and width.

We know that 2×4 = 8 and that 4 is twice as much as 2. Thus the 4 dimension corresponds to the height of the sail, and the 2 dimension corresponds to its width.

The sail is 4 m high.

12

step-by-step explanation:

12 + 5 = 17

12x2=24

24-7=17

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4
