Answer:
x =17
Step-by-step explanation:
Complementary angles add to 90
4x+ x+5 = 90
Combine like terms
5x+5 = 90
Subtract 5 from each side
5x+5-5 = 90-5
5x = 85
Divide by 5
5x/5 = 85/5
x =17
Answer:
B. 36
Step-by-step explanation:
Factoring 3x^2 + 12x + 36
3x^2 + 12x + 36
= 3(x^2 + 4x + 12)
<em>This is the most it can factor.</em>
None of the others factor.
By Question it's given that the sum of two numbers is 15 . And we need to find out the numbers. So ,
<u><em>Let </em><em>us </em><em>take</em><em> </em><em>:</em><em>-</em><em> </em></u>
- First number = x
- Second number = x + 1
<em><u>According</u></em><em><u> to</u></em><em><u> the</u></em><em><u> Question</u></em><em><u> </u></em><em><u>:</u></em><em><u>-</u></em><em><u> </u></em>
<em><u>Therefore</u></em><em><u> </u></em><em><u>:</u></em><em><u>-</u></em><em><u> </u></em>
- First number = 7
- Second number = 8
<u>Hence</u><u> the</u><u> </u><u>two </u><u>numbers</u><u> </u><u>are </u><u>7</u><u> </u><u>and </u><u>8</u><u>. </u>
85c - 0.5(85c) = 161.5
85c - 4.25c = 161.5
80.75c = 161.5
c = 161.5 / 80.75
c = 2............so she needs express proofreading
==================
x - 3 < -7 x + 5 > = 8
x < -7 + 3 x > = 8 - 5
x < -4 x > = 3
