Mathematics
1 answer:
Anit [1.1K]3 years ago
8 0

Answer:

(x - 9)(x + 2)

Step-by-step explanation:

Given

x² - 7x - 18

Consider the factors of the constant term (- 18) which sum to give the coefficient of the x- term (- 7)

The factors are - 9 and + 2, since

- 9 × 2 = - 18 and - 9 + 2 = - 7, thus

x² - 7x - 18 = (x - 9)(x + 2)

zloy xaker [14]

Answer:

15.32

Step-by-step explanation:

Eleven and seven-hundredths =11+\frac{7}{100}

(Here, \frac{1}{100} denotes the hundredth)

Four and twenty-five hundredth =4+\frac{25}{100}

Therefore,

Sum of Eleven and seven-hundredths added to four and twenty-five hundredth = 11+\frac{7}{100}+4+\frac{25}{100}

=15+\frac{32}{100}

=15+0.32

=15.32

How do I solve bh+hr=25 when solving for b
Alexxx [7]
Bh + hr = 25

you can factor out an h from the left side of your equation:

h(b + r) = 25 ... divide both sides by h
b + r = (25/h) ... subtract r
b = (25/h) - r
