The expression w4 - 36 is equivalent to
A (W2 – 18)(w2 – 18)
B (w2 + 18)(w2 – 18)
C (w2 - 6)(w2 – 6)
D (w2 + 6)(w2 – 6)
Answers
The equivalent expression of [tex]w^{4} -36[/tex] is [tex](w^{2} -6)(w^{2} +6)[/tex].
What is equivalent expression?Equivalent expressions are expressions that work the same even though they look different.
According to the given question.
we have an expression [tex]w^{4} -36[/tex]
The equivalent expression of the above expression can be given by
[tex]w^{4} -36[/tex]
⇒ [tex](w^{2}) ^{2} -(6)^{2}[/tex]
⇒[tex](w^{2}-6)(w^{2} +6)[/tex] (by using the property [tex]a^{2} -b^{2} = (a-b)(a+b)[/tex] )
Hence, the equivalent expression of [tex]w^{4} -36[/tex] is [tex](w^{2} -6)(w^{2} +6)[/tex].
Thus, option D is correct.

A rectangular prism has a volume of 640 cubic centimeters, a height of 5 centimeters,
and a length of 8 centimeters. What is the width of the rectangular prism in centimeters?
Answers
Answer:
10 cm
Step-by-step explanation:
The volume of a rectangular prism is calculated by multiplying the length, width and height together. So, to find one of the dimensions, all we need to do is divide the volume by the given dimensions. In this case we divide the volume, 640, by the height, 5, and length, 8.
The width, or w, is equal to 640 divided by 5 and 8.
w = 640 ÷ 5 ÷8
w = 80 ÷ 8
w = 10
The width is 10 cm.

(1, 3.5)
(9, -60.5)
(-8 -1)
(6, -30)
Answers
Answer: (6, -30)
Step-by-step explanation:
Substitute the points into the equation:
3.5 = -1/2(1^3) - 3(1) + 7 = 3.5: (1, 3.5) is on the graph.
-60.5 = -1/2 (9^2) -3(9) + 7 = -60.5: (9, -60.5) is on the graph.
-1 = -1/2 (-8^2) -3(-8) + 7 = -1. (-8, -1) is on the graph.
-30 = -1/2(6^2) -3(6) + 7 = -29 (6, -30) is not on the graoh.

How do you find the distance between points (5,1), (4,0)?
Answers
Answer:
To find the hypotenuse, you would use the formula a^2 + B^2 = C^2
That is the formula for the pythagorean theorem.
I suggest you first plot it on a graph, then could the units on the sides that make up the legs.
When you plot it, the legs are both 1 unit.
so it would be, following the formula:
1^2 + 1^2 = c^2
1 x 1 + 1 x 1 = c^2
2 = c^2
Then you square root:
√2 = √c^2
1.41421356 = c
1.41421356 rounded to the nearest tenth is 1.4.
So the length of (5,1), (4,0) is ≈1.4

Answers
Answer:
A) [tex]x = y^{2}[/tex]
Step-by-step explanation:
An equation is a function of [tex]x[/tex] when [tex]x[/tex] is the independent variable, that is:
[tex]y = f(x)[/tex] (1)
Where [tex]y[/tex] is the dependent variable.
According to this, [tex]x = y^{2}[/tex] does not represent a function of [tex]x[/tex], since the independent variable is a function of [tex]y[/tex], that is, [tex]x = f(y)[/tex]. Therefore, the correct answer is A.

Simplify the expression and then substitute the given number for the variable. For expression 8a2+6b+9a2+9b2+3b, find the value if a=2,b=−1.
Answers
Answer: 68
Step-by-step explanation:
Simplifying the expression:
= 8a² + 6b + 9a² + 9b² + 3b
Collect like terms
= 8a² + 9a² + 6b + 3b + 9b²
= 17a² + 9b + 9b²
We then substitute a=2,b=−1.
= 17a² + 9b + 9b²
= 17(2)² + 9(-1) + 9(-1)²
= 68 -9 + 9
= 68
1) One baseball team won 20 games throughout their entire season. Of all their games, this
team won 62.5% of them. Given this, how many games in total did this baseball team play
Answers
Answer: 32 matches
Step-by-step explanation:
Let the games in total that the baseball team played be represented by x.
Based on the information given in the question, we can form an equation as:
62.5% × x = 20
62.5/100 × x = 20
0.625 × x = 20
0.625x = 20
x = 20/0.625
x = 32
The team played a total of 32 matches.
