Answers
Answer:
x = -3 and x = 1
Step-by-step explanation:

12 - 8x = x² - 6x + 9
x² + 2x - 3 = 0
(x - 1)(x + 3) = 0

Answer:
I) 616
II) 4.53
Step-by-step explanation:
For the first one, just plug in 7 as R.
A = 4 x (22/7) x 7^2
A = 12.57142857 x 49
A = 616
For the second, one, put 452 4/7 as A.
452 4/7 also is 258.285
258.285 = 4 x (22/7) x r^2
258.285 = 12.57142857 x r^2
Divide both sides by 12.57142857
20.55372408 = r^2
Square root 20.55372408 for R.
4.533621519 = R
OR
4.53 = R

Por favor!! Es urgente doy corona plis La edad de Pedro es tres veces la edad de Jorge, la suma de ambas edades es 72 años. Halle ambas edades.
Answers
Answer:
Pedro age = 54 ; Jorge age = 18
Step-by-step explanation:
Pedro age = P
Jorge age = J
3J = P
J + P = 72
we have to substitute the value of P in the second equation
J + 3J = 72
we have solve the equation
4J = 72
J = 18
we have to subistute this value in the first equation
3*18 = P
P = 54

It was the day before the big U.S. History test. It was an open-note exam, so if students took good notes, they would probably get a good grade on it. The problem for Helga was that she waited until the last minute to review her notes—and they were terrible. In a panic, she called her best friend, Tracy, and asked her to make a copy of the notes she took so Helga could use the copy to take the test. Tracy always took detailed notes, and Helga knew she would get a good grade if she used the copy of Tracy’s notes. Why is this most likely a dangerous situation for both Helga and Tracy? They would put their education at risk. They would break their parents’ rules. They would put their friendship at risk. They would break the school laws.

A rectangle has an area of 54 square centimeters. The width is 3 more
than 1 times the length. Find the length and width, in centimeters, of the
triangle.
Answers
Answer:
W = 6
L = 9
Step-by-step explanation:
area = 54 = L x W
L = W + 3
substitute for L:
54 = W(W + 3)
W² + 3W = 54
W² + 3W - 54 = 0
(W + 9)(W - 6) = 0
W = 6
L = 6 + 3 = 9

25 = 5 + 4e
Solving
25 = 5 + 4e
Solving for variable 'e'.
Move all terms containing e to the left, all other terms to the right.
Add '-4e' to each side of the equation.
25 + -4e = 5 + 4e + -4e
Combine like terms: 4e + -4e = 0
25 + -4e = 5 + 0
25 + -4e = 5
Add '-25' to each side of the equation.
25 + -25 + -4e = 5 + -25
Combine like terms: 25 + -25 = 0
0 + -4e = 5 + -25
-4e = 5 + -25
Combine like terms: 5 + -25 = -20
-4e = -20
Divide each side by '-4'.
e = 5
Simplifying
e = 5

Answer:
(x + 1)(2x - 5)
Step-by-step explanation:
Assuming you require the expression factorised.
2x² - 3x - 5
Consider the factors of the product of the x² term and the constant term which sum to give the coefficient of the x- term.
product = 2 × - 5 = - 10 and sum = - 3
The factors are + 2 and - 5
Use these factors to split the x- term
2x² + 2x - 5x - 5 ( factor the first/second and third/fourth terms )
= 2x(x + 1) - 5(x + 1) ← factor out (x + 1) from each term
= (x + 1)(2x - 5) ← in factored form
