This equation simplified would be 2x^2.
Since we have terms that are not like (one has a variable and the other doesn't), we simply put them together when being multiplied.
x^2 * 2 = 2x^2
The time × 1.5=the distance
so 5×1.5=7.5
10×1.5=15
20×1.5=30
im a 7th grader doing 8th grade math.. just think
B=c-5
c+b=185
so, c+(c-5)=185
2c=190
c=95
b=90
As simple as that.
Answer:
Dimensions : 37.5 * 12.5
length : 37.5
width : 12.5
Step-by-step explanation:
let x = length and y = width
x = 3y based on info from problem
Perimeter = 2(length + width)
100 = 2(x + y)
substitute 3y for x
100 = 2(3y + y)
100 = 2(4y)
100 = 8y
y = 12.5
x = 3(12.5) = 37.5
Answer:
529 feet squared
Step-by-step explanation:
We know that the sides of a square are all the same length, and the formula to find the area of a square is length time width, so to find the area of the square we multiply 23 by 23, or square 23. 23 times 23 equals to 529 so the area of the square is 529 feet squared.
