Answer:
4(x - 5)(x - 8)
Step-by-step explanation:
Given
4x² - 52x + 160 ← factor out 4 from each term
= 4(x² - 13x + 40) ← factor the quadratic
Consider the factors of the constant term (+ 40) which sum to give the coefficient of the x- term (- 13)
The factors are - 5 and - 8, since
- 5 × - 8 = + 40 and - 5 - 8 = - 13, thus
x² - 13x + 40 = (x - 5)(x - 8)
Then
4x² - 52x + 160 = 4(x - 5)(x - 8)

Use the Pythagorean Theorem to determine if a triangle with sides 15 cm, 7 cm, and 16 cm is a right triangle.
Answer:
It is not.
Step-by-step explanation:
[tex]15^{2}[/tex]+[tex]7^{2}[/tex]=225+49=274
[tex]16^{2}[/tex]=256
274≠256
Answer:
No, this triangle is not a right triangle
Step-by-step explanation:
If (7 cm)^2 + (15 cm)^2 = (16 cm)^2, then this is a right triangle, by the Pythagorean Theorem. Otherwise it is not.
15^2 + 7^2 = 225 + 49 = 1225 = 35^2. This is FALSE, and so:
No, this triangle is not a right triangle

Which net matches the figure?
In the first image, notice that the figure is a cube
also known as a "square prism."
Since a cube is composed of square bases, we
want to find a net that is composed of all squares.
Notice that the option of the bottom left is composed of squares.
So this net matches the figure.

On a coordinate plane, trapezoid A B C D has points (negative 3, negative 2), (negative 1, 2), (3, 2), and (5, negative 2). Trapezoid ABCD is graphed in a coordinate plane. What is the area of the trapezoid? 16 square units 24 square units 32 square units 48 square units
Answer:
Correct option: second one -> 24 square units
Step-by-step explanation:
First we need to find the length of each side of the trapezoid, and we do that finding the distance between points:
AB = sqrt( (-1 - (-3))^2 + (2 - (-2))^2) = 4.4721
BC = sqrt( (3 - (-1))^2 + (2 - 2)^2) = 4
CD = sqrt( (5 - 3)^2 + (-2 - 2)^2) = 4.4721
DA = sqrt( (-3 - 5)^2 + (-2 - (-2))^2) = 8
The points B and C have the same y-coordinate, and the points D and A also have the same y-coordinate, so they are the bases of the trapezoid.
The height of the trapezoid is the difference in y-coordinate of points B and A:
height = 2 - (-2) = 4
So the area of the trapezoid is:
Area = (BC + DA) * 4 / 2 = (4 + 8) * 2 = 24 square units
Correct option: second one
Answer:
Its B

find the value of JW given that JW=6x+2 and JB=10x+1
The value of JW is 14 units.
What is a triangle?A triangle is a polygon with 3 sides. The area of a triangle with base b and height h is given by A = (1/2)bh.
Given that, JB is the median of the triangle and JW = 6x + 2 and JB = 10x + 1.
The distance between the centroid and a vertex of a triangle is 2/3 of the length of the median, therefore, it follows:
JW = (2/3)JB
Substitute the values:
6x + 2 = (2/3)(10x + 1)
18x + 6 = 20x + 2
2x = 4
x = 2
Substitute x = 2 into the expression for JW:
JW = 6(2) + 2
JW = 14
Hence, the value of JW is 14 units.

Can one please help me with this question
Answer:
254.34 cm^2
Step-by-step explanation:
Volume of cylinder = [tex]\pi r^{2} h[/tex]
We know that the diameter is 6, which means that the radius is 3 cm.
Now, it also tell us that that the height is triple the radius, this means that we multiply it by 3. Therefore, the height is 9 cm.
Now we know r = 3 cm and h = 9 cm, pi is assumed to 3.14 as well.
Substituting into the formula we will end up with 254.34 cm^2.

4(x + 6) = 32 What is x?
Answer: x = 2
Step-by-step explanation: To solve this equation, we start by distributing the 4 through the parentheses on the left side.
So we have 4(x) which is 4x and 4(6) which is 24.
So our equation now reads 4x + 24 = 32.
Solving from here, we subtract 24 from both sides to get 4x = 8.
Then divide both sides by 4 to get x = 2.

Rearrange making m the subject
Add 5n to both sides
3m = 11 + 5n ( divide both sides by 3 )
m = [tex]\frac{11+5n}{3}[/tex] , thus
m = g(n) = [tex]\frac{11+5n}{3}[/tex]
