Answer:
C
Step-by-step explanation:
Equation : -1x² - 14x + 2 = 0General Formula : b2-4ac=0a=-1, b= -14, c= 2Put the Value in General FormD = (-14)2 - 4 x -1 x 2D = 196--8D = 204
and the polynomial has 2 real roots
40 + 10x = 5x - 30
To begin isolating x, subtract 40 from both sides.
40 + 10x - 40 = 5x - 30 - 40
10x = 5x - 70
Subtract 5x from both sides.
10x - 5x= 5x - 70 - 5x
5x = -70
Finally, divide both sides by 5.
5x/5 = -70/5
x = -14
Answer:
x = -14
Answer:
50 ft
Step-by-step explanation:
For perimeter u add up all the sides and 15+15+10+10=50
