Answer:
Area of the rectangle is 10x²+7-6
Step-by-step explanation:
Area of rectangle is the product of its length and width
As length of given rectangle is 5x+6 and its width is 2x-3 the are is
(5x+3)(2x-3)
=5x·2x-5x+6·2x-6
=10x²-5x+12x-6
=10x²+7x-6
Answer: 10x^2+7x-6
(5x+6) * (2x-1)
10x^2-5x+12x-6
10x^2+7x-6
(Simple DMAS rules )
hope this helps :)
Answer:
let length is 3x
the width be x
perimeter of rectangle is 2(l+b)
24=2(3x+x)
24=2(4x)
24=8x
divide the both side by 8
x=3
therefore length is 3×3=9
width is 3
Answer:
Step-by-step explanation:
Speed v = distance d/time t
v = 14km/h, t = 2 1/2hr = 5/2hrs
: 14 = d/(5/2)
14 = 2d/5
14 × 5 = 2d
d = (14× 5)/2
d = 35km
