The answer would be A because if you combine all the like terms you will get A as a result.
-2x^2+8x-9+4x+7x^2+2
-2x^2+7x^2 combine both of these and it will get you 5x^2
And then you would do 8x+4x which would be 12x and lastly you would -9+2 which would be -7 so the answer is A.
Hope this helps!!
Answer:
A.
Step-by-step explanation:
an issue that negatively impacts a group of people.
<h3>Supplementary Angles:</h3>
Angles which adds up to 180°.
<h3>Given:</h3>
A = 2x + 8
B = 2x + 8
<h3>To Find:</h3>
The measurement of B.
<h3>Solution:</h3>
A + B = 180°
or, 2x + 8 + 2x + 8 = 180°
or, 4x + 16 = 180°
or, 4x = 180 - 16 = 164°
or, x = 164/4 = 41°
<h2>Answer:</h2>
B = 2x + 8 = 2(41) + 8 = 82 + 8 = 90°
<u>B</u><u> </u><u>=</u><u> </u><u>9</u><u>0</u><u>°</u>
Answer:
1. If x = 4 and y = 8, u = 3x - 4 would make sense because 3x, or 3 x 4 = 12
12 - 4 = 8 y = 8 (True)
2. m = 12 and n = 200 . n = 15m - 20 15 x 12 = 180 180 - 20 = 200 Would not make sense because 180 - 20 is 160 (False)
3. a = 5 and b = 48 b = 48 . 8a + 8 = 8 x 5 + 8 8 x 5 + 8= 48
(True)
4. G = 40 and h = 1000
H = 25g + 300
25g = 1000
1000+300= 1300, not 1000
(false)
