Step-by-step explanation:
taking common (a-b)
so we get the answer
150/4 = 37.5cm. You divide by four because there are four sides on a rectangle. But 37.5 is the cm of a square. Since it says one of the sides is 15cm greater, you subtract 37.5 - 15 = 27.5cm on 2 of the width. While the other 2 lengths are greater than the width by 15 cm, so you add 15 to 37.5 which gives you 52.5cm. So the 2 width are 27.5cm and the length is 52.5cm.
X = 20
Isolate the variable by dividing each side by factors that don't contain the variable.
x
=
20
Answer: 24 sq. ft
Step-by-step explanation: 20 x 36 - (36 - 20 / 2 ) x (20 - 14 )= 24 sq. ft
Answer:
The greatest common factor is 10
Step-by-step explanation:
Once you factor it out, you have :
10(x^2+5)
