Answer:
D
B
Step-by-step explanation:
1. x² - 5x = 14
x² -5x -14 = 0
x² +2x -7x -14 = 0
x(x + 2) -7(x + 2) = 0
x - 7 or x + 2 = 0
x = 7 or x = -2
2. y² + 6y + 9 = 49
y² + 6y +9 -49 = 0
y² +6y -40 = 0
y² +10y -4y -40 = 0
y(y + 10) -4(y + 10) = 0
y -4 or y + 10 = 0
y = 4 or y = -10
X intercept is 7/2, y intercept is -7. hope this helps
<h3><u>given</u><u>:</u></h3>
each interior angle= 168°
<h3><u>to</u><u> </u><u>find</u><u>:</u></h3>
the number of sides the polygon has.
<h3><u>solution</u><u>:</u></h3>
180- 360/n= 168
12= 360/n
n= 360/12
n= 30
<u>therefore</u><u>,</u><u> </u><u>the</u><u> </u><u>polygon</u><u> </u><u>has</u><u> </u><u>30</u><u> </u><u>sides</u><u>.</u>
1/20 mile. divide 1/4 by 5 by fliping the division sign and 5. (1/4)(1/5)=1/20
