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)

Can someone help me please!!?? Eleven and seven-hundredths added to four and twenty-five hundredth the sum is

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
