Answer:
C. 3(2x + 5y) is the algebraic expression equivalent to the expression
Step-by-step explanation:
From the question, the given expression is 6x + 15y.
Factorizing this expression gives 3(2x + 5y). Hence, the algebraic expression equivalent to the expression 6x + 15y is 3(2x + 5y). (Option C).
Checking the remaining options
A. 3(2x - 5y)
Expanding this gives 6x - 15y. It is not equivalent to the given expression
B. 3(5x - 2y)
Expanding this gives 15x - 6y. It is not equivalent to the given expression
D. 3(5x + 2y)
Expanding this gives 15x + 3y. It is not equivalent to the given expression.
Hence, C. 3(2x + 5y) is the algebraic expression equivalent to the expression.
Answer:
The area for a square is given by:
![A = x^2](https://tex.z-dn.net/?f=%20A%20%3D%20x%5E2)
And we can find the dimension for one side like this:
![x = \sqrt{A}](https://tex.z-dn.net/?f=%20x%20%3D%20%5Csqrt%7BA%7D)
Replacing we got:
![x = \sqrt{49 ft^2}= 7ft](https://tex.z-dn.net/?f=%20x%20%3D%20%5Csqrt%7B49%20ft%5E2%7D%3D%207ft)
Then since we are interested in the how many feet of fencing does she need, we can find the perimeter given by:
and replacing we got:
![P = 4*7 ft = 28 ft](https://tex.z-dn.net/?f=%20P%20%3D%204%2A7%20ft%20%3D%2028%20ft)

if grinch is a person like shown in the story,
the fraction would be
, this represents the grinch among the people in Whoville.
<span> (4,-2) (-3,2) (3,4) (1,1)
In reality, it is already a function, because for every x only one corresponding value of y.
We do not see any repeating values of x, so this set is already function. We do not have to remove anything.</span>
