Factor completely. x2+7x−18

1 answer:

4 0

Hi there!

In order to factor, we need to find two terms that multiply to the c term (-18) but add to the b term (7).

9*-2=-18
9+-2=7
Therefore the factored form would be y=(x+9)(x-2)

Hope this helps!

Evaluate the expression. [(8 x 7) – 2): 9

frozen [14]

Answer:

☑ Answer is 6

Step-by-step explanation:

${ \tt{ \{(8 \times 7) - 2 \} : 9}} \\ = { \tt{(56 - 2) :9 }} \\ = { \tt{54 :9 }}$

» But this is a ratio, so it can be expressed in terms of fractions:

$= { \tt{ \frac{54}{9} }} \\$

» Divide both the denominator and numerator by 9:

${ \tt{ = \frac{54 \div 9}{9 \div 9} }} \\ \\ = { \tt{ \frac{6}{1} }} \\ \\ = 6$
