The rectangular backboard of a basketball court needs to be assembled. its area is given as 18,900 cm2 and the width as 1.8 m. what is the backboard’s length in metres?

Step-by-step explanation:

Area of a rectangular figure is given by length times width

means

Area = length * width

we are given that the Area = 18,900 cm^2

width =1.8 m =1.8*100=180cm

using the formula and the given values we get

so simplifying the equation we get

length = 105 cm

length = 1.05 m

correct answer:

i^31 = -i

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10
