Step-by-step explanation:
In 13 - 17
Consider the factors of the constant term which sum to give the coefficient of the x- term
13
x² - x - 42 = (x - 7)(x + 6)
15
x² + x - 6 = (x + 3)(x - 2)
17
x² - 27x + 50 = (x - 25)(x - 2)
19
r² - 25 ← is a difference of squares and factors in general as
a² - b² = (a - b)(a + b) , thus
r² - 25
= r² - 5² = (r - 5)(r + 5)
<span>What is the value of c?
5x2 - 3y2 - 20x + 6y + 2 = 0
Select one:
a. 2
b. 4
c. √4
d. √8
This was an older question and someone said the answer was D and I got it right.</span>
Answer:
2.85
Step-by-step explanation:
You divide 14.25 by 10 then multiply that by 2
equation: (14.25 divided by 10)2
Answer:
5 : 4
Step-by-step explanation:
To simplify the ratio , find the greatest common factor of 60 and 48, then divide both parts of the ratio by it
the greatest common factor of 60 and 48 is 12, hence
60 ÷ 12 : 48 : 12 = 5 : 4 ← in simplest form
Answer:
12 inches
Step-by-step explanation:
30-13=17
17-5= 12
Use information about the triangle's perimeter, to find the side length of C.
If the triangle frame is a right triangle, than you could use the Pythagorean Theorem and use the following formula, a^2 + b^2 = c^2, to find the measure of side c.
Have a great rest of your day, and I hope this helps!
