Answer:

3.75

Step-by-step explanation:

1.5 equals 30 ft so x2 equals 60 then 15 is half of 20 so half of 1.5 in is .75 so 3 plus .75

Which of the following best describes the English expression the quotient of four and the sum of a number and three? A. 4/x+3 B.
Tems11 [23]
Quotient means division, which is obvious by all the division answers. 
It says "Quotient of 4 AND ..." which means that four will be on top and everything else will be on the bottom. 

So now you have:
\frac{4}{?}
four over something unknown. 

Reading the rest of the question, "the sum of a number and three"
Sum means addition, again obvious by the answer choices. 
"a number" is an unknown, so we can set that to x
and this x is being added to by three, so therefore 
x+3 would be in your denominator. 

You final equation should look like this:;
\frac{4}{x+3}
OR answer choice A

Write the expression. Then, check all that apply. twice the difference of a number and six A 2-column table with 4 rows. Column
Pie

The statements that apply to the algebraic expression are

  • Replace “a number” with the variable, n.
  • The two operations are multiplication and subtraction.
  • The constants are 2 and 6.
  • The expression is written as 2(n – 6)
<h3 /><h3>How to determine the algebraic expression?</h3>

The complete question is added as an attachment

The statement is given as:

Twice the difference of a number and six

Represent the number with n.

So, the statement becomes

Twice the difference of a n and six

Twice means 2 *

So, we have

2 * difference of a n and six

Express difference as minus i.e. -

So, we have

2 * (n - 6)

Hence, the expression is written as 2(n - 6)

Multiply and simplify. 3(x2 + 5)(x2 - 5)
Luba_88 [7]

Answer:

3 x^4 + -75

Step-by-step explanation:

Expand the following:

3 (x^2 + 5) (x^2 - 5)

(x^2 + 5) (x^2 - 5) = (x^2) (x^2) + (x^2) (-5) + (5) (x^2) + (5) (-5) = x^4 - 5 x^2 + 5 x^2 - 25 = x^4 - 25:

3 x^4 - 25

3 (x^4 - 25) = 3 x^4 + 3 (-25):

3 x^4 - 25×3

3 (-25) = -75:

Answer:  3 x^4 + -75
