Answer:
c) (x +2)
e) ( 5 x -2)
Step-by-step explanation:
<em><u>Explanation</u></em>:-
Given equation 5 x² + 8 x – 4
The factors of - 20 = 10 × - 2
⇒ 5 x ² + 10 x - 2 x - 4
⇒ 5 x ( x + 2) - 2 ( x + 2)
⇒ (5 x - 2 ) ( x + 2)
The multiplies of given equation
5 x² + 8 x – 4 = (5 x - 2 ) ( x + 2)
To find the percent of 15 out of 60, you have to divide fifteen by sixty.
Then, you multiply your answer by 100. (We do this because 100 percent is a exact amount. 100% of sixty is...well, sixty.)
15 / 60 = 0.25
Now, we can multiply 0.25 by 100:
0.25 * 100 = 25 (basically just moving the decimal two places to the right.)
Next, add a percent sign:
25%, is your answer.
15 is 25% of 60.
1/8 + 1/4
the least common multiple of 8 and 4 is 8. Convert 1/8 and 1/4 to fractions with denominator 8.
1/8 + 2/8
Because 1/8 and 2/8 have the same denominator, add them by adding their numerators.
1+2/8
add 1 and 2 to get 3
3/8 or 0.375
