Since (20) = (-3) [we can cross multiply]
(x²- 25) (5-x)
⇒ (20)(5 - x) = (-3)(x² - 25) [expand the brackets]
⇒ 100 - 20x = -3x² + 75 [make the equation equal to zero]
⇒ 3x² - 20x + 25 = 0 [expand the middle term using
appropriate factors of the product
of the terms a and c (3 × 25)]
⇒ 3x² - 15x - 5x + 25 = 0 [factorize the terms]
⇒ (3x - 5 ) (x - 5) = 0 [using the knowledge that for the
produc to be 0, one of terms
must be zero]
⇒ (3x - 5 ) = 0 OR (x - 5) = 0 [solve for x in each case]
⇒ x = ⁵/₃ OR x = 5

Find rational zeros
Answer:
(x - 2) • (x - 4) • (x - 8)
Step-by-step explanation:
The first term is, x2 its coefficient is 1 .
The middle term is, -6x its coefficient is -6 .
The last term, "the constant", is +8
Step-1 : Multiply the coefficient of the first term by the constant 1 • 8 = 8
Step-2 : Find two factors of 8 whose sum equals the coefficient of the middle term, which is -6 .
-8 + -1 = -9
-4 + -2 = -6 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -4 and -2
x2 - 4x - 2x - 8
Step-4 : Add up the first 2 terms, pulling out like factors :
x • (x-4)
Add up the last 2 terms, pulling out common factors :
2 • (x-4)
Step-5 : Add up the four terms of step 4 :
(x-2) • (x-4)
Which is the desired factorization

A = 728.85cm³
solve for t
3/4t=1/4
PLEASE HELP
Answer:
1/3
Step-by-step explanation:
1) Simplify 3/4t to 3t/4
3t/4 = 1/4
2) Multiply both sides by 4
3t = 1/4 x 4
3) Cancel 4
3t = 1
4) Divide both sides by 3
t = 1/3
PLS PLS help! A computer and printer cost a total of $1299. The cost of the computer is two times the cost of the printer. Find the cost of each item.
Answer:
Computer is $866
Printer is $433
Step-by-step explanation:
We can form two equations given our variables:
Let's assume the computer=C and the Printer=P.
1) C+P=1299
2) 2P=C
Now we just plug in the 2nd equation into the 1st.
(2P+P)=1299
3P=1299
P=1299/3
P=433
Now that we know the value of the printer, we can subtract that from the total price:
1299-433=866
C=866

Trapezoid LMNO is dilated by a scale factor of 3/4 to form trapezoid L'M'N'O'. Side O'L' measures 6. What is the measure of side OL?
Dilating a trapezoid involves changing its size.
The measure of side OL is 8
The given parameters are:
[tex]\mathbf{O'L' = 6}[/tex]
[tex]\mathbf{k = \frac 34}[/tex]
Side length O'L' is calculated using:
[tex]\mathbf{O'L' = OL \times k}[/tex]
Make OL the subject
[tex]\mathbf{OL = \frac{O'L'}{k}}[/tex]
So, we have:
[tex]\mathbf{OL = \frac{6}{3/4}}[/tex]
[tex]\mathbf{OL = 8}[/tex]
Hence, the measure of side OL is 8

Answer:
A=2 B=1
Step-by-step explanation:
B is distributive because you have to foil the x out of the parenthesis
A is because when three or more numbers are added (or multiplied), the sum (or the product) is the same regardless of the grouping of the addends.
Here are two spinners (picture attached)
Step-by-step explanation:
you can subtract the spinner a from spinner b and then find the probability

Given quadrilaterals
ABCD and LMNO, and AC = LN, how can you
show that the corresponding angles of the
quadrilaterals are congruent?
Answer:
I think it would be by SSS
Step-by-step explanation:
SSS tells that if three sides of a triangle are congruent to three sides of another triangle, then the two triangles are congruent. The lines on the triangles show that they are congruent, so by looking at the sides, the triangles are congruent. If the sides are the same, then the angles are the same.
