Mathematics
1 answer:
Natasha_Volkova [10]3 years ago
4 0

Answer:

(x - 9)(x + 8)

Step-by-step explanation:

Given

x² - x - 72

Consider the factors of the constant term (- 72) which sum to give the coefficient of the x- term (- 1)

the factors are - 9 and + 8, since

- 9 × 8 = - 72 and - 9 + 8 = - 1, thus

x² - x - 72 = (x - 9)(x + 8)

Um, ok I'm not entirely sure what number sets you need, but I'll do my best.

Integers: 5, -3, 0, 1, -12

Fractions: 1/2, 4 1/2

Decimals: 14.2, -19.4, 0.125

All of the above can also be considered Rational numbers. Rational numbers are numbers that can be expressed as a fraction. All For example, 14.2 is 14 1/5.

Irrational number: \pi

Pi is irrational. It cannot be expressed as a fraction.

You can buy 3 T-shirts for $24. Write a proportion that gives the cost c of buying 7 T-shirts. $$
Rudiy27

Answer:

3/24 = 7/x

c = $56

Step-by-step explanation:

A percent proportion is just basically a ratio, I could also write this as         3:24 = 7:x, it really doesn't matter. What does matter is that this is considered a percent proportion. Now, to solve a percent proportion, we have this formula.

a/b = c/d

Say b is the unknown value, we would do (a*d)/c, say a was the unknown value, we would do (b*c)/d, Basically, A and D are linked together and B and C are linked together so you take the two values that are linked together first, multiply them together, and divide by the pair that has a partner that is unknown.
