Answer:
1) (2x + 2)(x + 2)
2) 2(x + 1)(x - 1)
3) (x^2 + 3)(x^2 - 3)
4) 2x(x + 5)(x - 2)
5) (5x + 2y)(5x - 2y)
Step-by-step explanation:
1)
2x^2 + 6x + 4
= 2x^2 + 4x + 2x + 4
= 2x(x + 2) + 2(x + 2)
= (2x + 2)(x + 2)
2)
2x^2 - 2
= 2(x^ 2 - 1) (The difference of two squares)
= 2(x + 1)(x - 1)
3)
x^4 - 9 (The difference of two squares)
=(x^2 + 3)(x^2 - 3)
4)
2x^3 + 6x^2 - 20x
= 2x(x^2 + 3x - 10)
= 2x(x + 5)(x - 2)
5)
25x^2 - 4y^2 (The difference of two squares)
= (5x + 2y)(5x - 2y)
Step-by-step explanation:
Hey there!
0.3 = 3/8 (equal to eachother)
Reason: (<u>3</u><u>/</u><u>8</u><u> </u><u>=</u><u> </u><u>0.375</u><u>)</u>
<u>So</u><u>,</u><u> </u><u>0</u><u>.</u><u>3</u><u> </u><u>is</u><u> </u><u>equal</u><u> </u><u>to</u><u> </u><u>eachother</u><u>. </u>
<u>0</u><u>.</u><u>3</u><u>=</u><u>0</u><u>.</u><u>3</u>

The answer is the first option, you multiply 14^2 by 9
Answer:
(5/12)d - (23/36)g
Step-by-step explanation:
First you can eliminate g and -g to get (1/6)d - (3/4)g + (1/9)g + (1/4)d. Then you need to get common denominators to add like terms together.
1/6 = 4/24 and 1/4 = 6/24. Add them together to get (10/24)d or (5/12)d.
-3/4 = -27/36 and 1/9 = 4/36. Add them together to get (-23/36)g.
So in standard form, (5/12)d - (23/36)g
