Answer:
Step-by-step explanation
Perimeter of a rectangle =2(length +breadth)
90m = 2{(36x+2) + (2(x+2)}
Opening the inner brackets,
90 = 2{36x +2+2x +4}
90 = 2{38x +6}
Open the brackets
90 = 76x + 12
Collect like terms
90 - 12 = 76x
78=76x
Divide 78 by the coefficient of x
x = 78÷76
x =1.03m (2d.p)
Substitute the value of x into the expressions for the two sides of the rectangle
36x+2 =(36×1.03) +2= 37.08+2=39.08m
2(x+2)= 2(1.03+2)= 2(3.03) =2×3.03= 6.06m
The approximate values of the two sides of d rectangular field are 39.08m and 6.06m
4 feet 8 inches
______________________________________________________________
First find how many inches are in 4 feet + 8 inches. There are 12 inches in 1 foot. Multiply 4 x 12 = 48. Add 8 to 48 = 56. Laney's height in inches is 56 inches.
______________________________________________________________
There are 2.54 centimeters in 1 inch. Multiply 56 x 2.54 = 142.24.
______________________________________________________________
Laney's height is 142.24 centimeters.
First, get y by itself by adding 8 to both sides: y=-x+8
According to the equation, the slope is -1 and the y-intercept is 8 when we match it up with y=mx+b form.
