1. The simplified form of -x + 4 is: B. - x + 4
2. B. 4 less than m
3. The property that illustrates the expression, 3 + x = x + 3, is: D. cumulative property of addition.
4. √3
<h3>What is the Commutative Property of Addition?</h3>
According to the Commutative Property of Addition, how numbers that are are added are ordered do not change or affect the sum of the numbers. For example, a + b = b + a.
1. To simplify -(x - 4) using the distributive property:
= -1(x) -1(-4)
= -x + 4
Therefore, the simplified form of -x + 4 is: B. - x + 4
2. m - 4 can be written as a phrase as: B. 4 less than m
3. The property that illustrates the expression, 3 + x = x + 3, is: D. cumulative property of addition.
4. Irrational numbers cannot be expressed, as a simple fraction. √3 cannot be expressed in simple fractions. Therefore, √3 is classified as: B. irrational.

Answer:
4 feet.
Step-by-step explanation:
Please consider the complete question.
Angela makes a pillow in the shape of a wedge to use for watching tv. The pillow is filled with 12 cubic feet of fluffy material. The base is 3 ft, the height is 2 ft. What is the length measure?
We know that a wedge is in form of triangular prism, so the volume of wedge will be equal to volume of triangular prism.

Upon substituting our given values in above formula, we will get:




Therefore, the length of the pillow is 4 feet.
Answer:
D ( x -2i sqrt(2)) ( x+ 2i sqrt(2))
Step-by-step explanation:
x^2 + 8
We want to factor so rewrite as squares
x^2 + (2sqrt(2))^2
Rewrite with a subtraction sign i^2 = -1
x^2 - (2*i*sqrt(2))^2
This is the difference of squares
a^2 - b^2 = ( a-b) (a+b)
( x -2i sqrt(2)) ( x+ 2i sqrt(2))
