Answer:
-a^4b + b^3 - 8c^2
Step-by-step explanation:
Sum of
3a^4b-4b^3+c^2 + 6a^4b+3b^3-6c^2
= 3a^4b + 6a^4b - 4b^3 + 3b^3 + c^2 - 6c^2
= 9a^4b - b^3 - 5c^2
Sum of
6a^4b-4b^3-4c^2 + 2a^4b+4b^3+7c^
= 6a^4b + 2a^4b - 4b^3 + 4b^3 - 4c^2 + 7c^2
= 8a^4b + 3c^2
Subtract
8a^4b + 3c^2 - (9a^4b - b^3 - 5c^2)
= 8a^4b + 3c^2 - 9a^4b + b^3 + 5c^2
= 8a^4b - 9a^4b + b^3 + 3c^2 + 5c^2
= -a^4b + b^3 - 8c^2
The circumference of a circle is 64. What is the radius of the circle?
Triangle S R Q is shown. Angle S R Q is a right angle. An altitude is drawn from point R to point T on side S Q to form a right angle. The length of S T is 9, the length of T Q is 16, and the length of R Q is x.
What is the value of x?
12 units
15 units
20 units
24 units
Answer:
the actual answer is 20 units
Step-by-step explanation:
The value of x which is equal to length RQ is 20 units.
The given parameters;
Length of ST = 9 Length of TQ = 16Length of RQ = xFrom the given triangle we can apply similar triangle property as follows;
[tex]\frac{base \ of \ triangle \ SRQ}{hypotenuse \ of \ triangle \ SRQ} = \frac{base \ of \ triangle \ RTQ}{hypotenuse \ of \ triangle \ RTQ} \\\\\frac{RQ}{SQ} = \frac{TQ}{RQ} \\\\\frac{x}{(9 + 16)} = \frac{16}{x} \\\\x^2 = 25 \times 16\\\\x = \sqrt{25 \times 16} \\\\x = 5 \times 4\\\\x = 20 \ units[/tex]
Thus, the value of x which is equal to length RQ is 20 units.

The Perimeter of the scalene triangle is 54.6cm
Which equation can be
used to find the value of b if side a measures 8.7 cm?
a 8.7+b=54.6
b 17.4+ b = 54.6
c 26.1 + b = 54.6
d 34.8+b =54.6
Answer: B. 17.4+b=54.6
Step-by-step explanation:
Edgen 2023
The equation can be used to find the value of b is 54.6 = 34.8 + b.
We have,
The border of the triangle is54.6 cm
and side a = 8.7 cm,
So, Perimeter = sum of the lengths of the three sides
54.6 = a + 3a + b
54.6 = 4a + b
We know a= 8.7 then
54.6 = 4(8.7) + b
54.6 = 34.8 + b
Therefore, the needed equation is54.6 = 34.8b.

f (x) = -x2 + 164x - 64, f(x) = -4x2 - 10x + 84, f(x) = 3x² + 24.
Answer:
You need to ask a question for someone to answer it.
Are you looking for their derivatives?
-x² + 164x - 64 => -2x + 164
-4x² - 10x + 84 => -4x - 10
3x² + 24 => 6x
Indefinite Integrals?
-x² + 164x - 64 => -x³/3 + 82x² - 64x + C
-4x² - 10x + 84 => -4x³/3 - 5x² + 84x + C
3x² + 24 => x³ + 24x + C
Want them factored?
-x² + 164x - 64 => has no factors
-4x² - 10x + 84 => 2(2x - 7)(x + 6)
3x² + 24 => 3(x² + 8)
We can't ensure a proper answer if you don't ask the question.

Which graph represents f(x) and the inverse f^-1(x)
Answer:
D
Step-by-step explanation:
The inverse or f⁻¹(x) of a function f(x) is the graph being reflected over the line y = x.
For A, f(x) is reflected over the x-axis.
For B, f(x) is rotated about a point.
For C, f(x) reflected over the y-axis.
And for D, f(x) is reflected over the line y = x.
So, the graph that represents f(x) and its inverse f⁻¹(x) is choice D.
4. The length of a rectangle is one more than twice the width. The area is 105 in?.
Find the WIDTH of the rectangle. *
9514 1404 393
Answer:
7 in
Step-by-step explanation:
For width w in inches, the length is given as 2w+1. The area is the product of length and width, so we have ...
A = LW
105 = (2w +1)w
2w^2 +w -105 = 0
To factor this, we're looking for factors of -210 that have a difference of 1.
-210 = -1(210) = -2(105) = -3(70) = -5(42) = -6(35) = -7(30) = -10(21) = -14(15)
So, the factorization is ...
(2w +15)(w -7) = 0
Solutions are values of w that make the factors zero:
w = -15/2, +7 . . . . . negative dimensions are irrelevant

Help pls!! Find the value of x and m
Answer:
The answer's the third one listed.
Step-by-step explanation:
The equation to solve for x is:
6x + 16 + 10x - 6 + 90 = 180
16x + 100 = 180
16x = 80
x = 5
To solve for angle BCD, just substitute 5 for x
m = 10(5) - 6
m = 50 - 6
m = 44
