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)
Answer:
c = -64
Explanation:
c/(-4) = 16
multiply the equation by -4,
c/(-4) × (-4) = 16 × (-4)
c = 16 × (-4)
c = -64
Answer:
49
Step-by-step explanation:
49 hamburguers (of 3/4 pound)
Step-by-step explanation:
3/4 pound is equal to 0.75 pound
37 1/3 pounds of meat is equal to
37 + 1/3 pound = 37.3333 pounds
To find how much hamburguers can be made, we need to divide
37.3333 pounds/ 0.75 pounds
37.3333 pounds/ 0.75 pounds = 49.777777
(We need to round to the lowest number)
This means that 49 hamburguers could be made
