2x² + 3x - 5 = 0
a=2, b=3, c=-5
D = b² - 4ac = 3² - 4*2*(-5) = 9 + 40 = 49
Answer:50.18
Step-by-step explanation:
8x+17+9x+11=102
17x+28=102
-28. -28
17x=74
<CAD=9x+11=50.18
x=74/17
Answer:
19/36 more than yesterday
Step-by-step explanation:
Since the denominators are different, multiply each fraction by the denominator of the other to be the same.
1/4 * 9 = 9/36
7/9 * 4 = 28/36
Now that the denominators are the same, you can subtract:
28/36 - 9/36 = 19/36
Answer: 28
Step-by-step explanation:
Since this is an isosceles triangle, two of the angles are congruent.
180 - 124 = 56
56/2 = 28
I hoped this helped it's basically the numbers outside that are across from each other
for ex. b and g are alterate angles (just remember they are outside and opposite)
