Since the angles sum of △ is 180°,here's the equation:
60°+65°+(8x+7)=180°
8x+7=180°-60°-65°
8x=55-7
x=48/8
x=6
Thus,the answer is x=6
Hope it helps!
Answer:
$5.20
Step-by-step explanation:
Talked on the phone for 14 minutes .
14 - 3 = 11
11 x .35 = 3.85
3.85 + 1.35 = 5.2
The given expression is
-2x² + 17 - 15x + 7xy
The algebraic expression may be written as
-2x² + 7xy - 15x + 17
The constant term does not contain either x or y.
Therefore 17 is the constant term.
Answer: 17
Answer:
<em>5x² + 10x + 2 </em>
Step-by-step explanation:
g(x + 1) = 5(x + 1)² - 3 = 5( x² + 2x + 1 ) - 3 = <em>5x² + 10x + 2</em>
