Answer: x = 6.8
or x = 102/15
Step-by-step explanation:
30x=204
204/30
simplify!
16x + 40y.....GCF is 8
8(2x + 5y) <==
Answer:
the answer is a equation
Step-by-step explanation:
because u supposed to make it a equation in order for it to be a expression.
hope you get it right!!!!!!!!
The general equation for computing the circumference of a circle is

, where C is the circumference, and d is the diameter. (You might also see the equation as

where r is the radius, because

)
Computing the circumferences of the two circles, we get:


.
To calculate the ratio of two numbers, we can divide one by the other. You can look at this as "How many times does the denominator fit in the numerator?"

So the circumference of the complex impact crater is 2 times greater than the circumference of the simple impact crater.
Answer:
(3x - 25y)(3x + 25y)
Step-by-step explanation:
9x² - 625y² ← is a difference of squares and factors in general as
a² - b² = (a - b)(a + b)
Given
9x² - 625y²
= (3x)² - (25y)²
= (3x - 25y)(3x + 25y)
