△ ABC ~ △DEF The perimeter of △ ABC is 6 and its area is 5The perimeter of △DEF is 18 and its area is x^2+91.) Determine the scale factor of △DEF to △ ABC :2.) let b represent the base of △ ABC and h represent height. Write expressions to represent the base and height of △DEF. Base: Height:3.) Use these expressions along with the information above to find all values of x that satisfy the given conditions and calculate the area of △DEF X=4.) area of △DEF=5.)What is the ratio of the area of △DEF to △ ABC?

step-by-step explanation:

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm

no one knows lol

step-by-step explanation:

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w
