If one length is 'x cm' long, and the other is '3x cm' long, the combined length would be (x + 3x) cm long, or 4x cm.
Answer:
The equivalent expression is
A is correct
Step-by-step explanation:
We are given two complex number and need to multiply it. To find equivalent fraction.
Using Binomial product property: (a+b)(c+d)=ab+ad+bc+bd
Combine the like term and simplify
Hence, The equivalent expression is
One width and one length is half the perimeter.
90/2 = 45
Let the width = X
the length is 2 times the width so 2X
The sum of the two equals 45"
2X + X = 45
Simplify:
3x = 45
Divide both sides by 3:
x = 15
The width is 15 inches
Length = 30 inches.
Area = Length x width = 15 x 30 = 450 in^2
The area 450 in^2
