2x + 2(x + 2) = 24
2x + 2x + 4 = 24
4x = 24 - 4
4x = 20
x = 20/4
x = 5
The value of x that holds true for the equation is : x = 5.
So the width of the rectangle is 5 inches and the length is (x + 2 = 5 + 2) = 7 inches
Answer:
18,000 meters
Step-by-step explanation:
We know:
Substitute:
{ v = 4 ⇒ INTO FORMULA ⇒ D = V × T : D = 4 × 24
{ t = 24
Cross out the common factor:
⇒ 6 × 3000
Calculate the product or quotient:
⇒ 18,000
Answer:
y=400/300x
Step-by-step explanation:
Hello,
There is a mistake: it is 816 cm² !!! (an area)
length are multiplied by 2,
so area are mutiplied by 2²=4
Area B=816*4=3264 (cm²)
