Express your length and width as algebraic expressions:
width = x
length = 4x
Use the formula for the perimeter of a rectangle to solve for x:
perimeter = 2(length) + 2(width)
50 = 2(4x) + 2(x)
50 = 8x + 2x
50 = 10x
5 = x
The width (x) is 5 feet and the length (4x) is 20 feet.
3s+28=85, take away 28 from both sides of the equals to give you 3s=57, divide by 3 on both side to give you s=19.
Sowe are going to work backward first were going to get rid off the negative 54 by adding it to the 0 making it 6x^2 =54 now were going to move the 6 by dividing both sides by 6 making it x^2=9 3 squared =9 so the variable is 3
Answer:
Radius = 7.995944341
Step-by-step explanation:
You use the circumference formula. C=2πr
Since you have the circumference 50.24 cm. You plug in the circumference.
50.24 = 2πr
You divide by 2 and get 25.12.
25.12 = πr
Then, you divide 25.12 by π.
Your answer is
7.995944341 = r
The given expression is
We can write 8 as cube of 2, 16 ad fourth power of 2, 12 as square of 2 times 3 and 81 as fourth power of 3, that is
In case of two powers, we have to multiply them.
Simplifying the exponent, will give
