Answer:
Step-by-step explanation:
Given x^2+4x+13=0, find the complex roots. The best approach here is to use the quadratic formula. Note that a = 1, b = 4 and c = 13.
Thus, the discriminant, b^2 - 4ac, is (4)^2 - 4(1)(13) = 16 - 52 = -36, and the square root of that is plus or minus i√36, or plus or minus 6i.
plus or minus i√
Answer:
522.60, hope that helps! (UwU)=/
Step-by-step explanation:
pencils: $4.10 * 6 ===> $24.60
pens: $6.50 * 12 ===> $78
notebook paper: $105 * 4 ===> $420
pencils + pens + notebook paper = total cost
24.60 + 78 + 420 = 522.60
The answer is D .............
Answer:
12
Step-by-step explanation:
First, find the total number of vehicles sold.
15 SUVs were sold, and 80 others were sold
15+80
95
So, 95 vehicles were sold in total.
Now we can make a proportion
15 out of 95 vehicles were SUVs, and we can expect x out of 76 vehicles to be SUVs
15/95=x/76
Cross multiply
95*x=15*76
95x=1140
To solve for x, we need to get x by itself. Since x is being multiplied by 95, divide both sides by 95. This will cancel out the 95, and leave x isolated.
95x/95=1140/95
x=12
So, 12 out 76 vehicles should be SUVs
