Width=x
length=2x+5
perimeter of a rectangle=2(length)+2(width)
We can suggest this equation:
88=2(2x+5)+2x
88=4x+10+2x
6x=88-10
6x=78
x=78/6
x=13
width=x=13
length=2x+5=2(13)+5=26+5=31
Answer: the width would be 13 cm.
Answer:
100 m3
Step-by-step explanation:
2*5*10 = 10*10 *100
2x+13
X= a number
2(a number) + 13
Thank you!
Answer:
y = -3x + 3
Step-by-step explanation:
Perpendicular slope: -3
y -(-3)= -3(x-2)
y+3= -3x + 6
y = -3x + 3
Answer:
x^2+y^2=r^2 is quation of circle whose centre is (0,0)
