Answer:
No
4x squared + 8x + 3 =
4x squared: 16x
16x + 8x + 3
add 16 and 8 = 24x + 3 and that's your answer
38 is 10 more than 1/3 of 21
If this is suppose to be 239%....
change to a fraction to look like this 238/100. This number cannot be reduced, so the common fraction is 239/100.
to make it a mixed number, you would simply divide 239 by 100. Your answer would come out to 2 with a remainder of 39. Put the remainder over the divisor and your answer for a mixed number will be 2 and 39/100.<span />
Two angles are supplementary when they <span>add up to 180 degrees.
x = angle
19x-60 = </span><span>supplement angle
x + 19x - 60 = 180
20x = 180 + 60
20x = 240
x = 240/20
x = 12</span>° ← answer
Given equation : y=ax^2
Taking a to the other side we have, x^2=(1/a)*y
This equation describes a parabola that opens up.
When a is negative, the focus is on the negative y-axis, therefore, the parabola opens down.
The answer is a. down.
