Answer:

1) ∫ x² e^(x) dx

4) ∫ x cos(x) dx

Step-by-step explanation:

To solve this problem, eliminate the choices that can be solved by substitution.

In the second problem, we can say u = x², and du = 2x dx.

∫ x cos(x²) dx = ∫ ½ cos(u) du

In the third problem, we can say u = x², and du = 2x dx.

∫ x e^(x²) dx = ∫ ½ e^(u) du

Opposite sides are parallel.

in a rhombus and square all sides are equal so it isn't those.

PLEASE HELPP ME IT"s DUE TODAY!!!!!
pishuonlain [190]

Answer:

since -5 and -5 are the same number, they are on the same y axis so the only distance we need to calculate is between the X coordinates

so when looking for distance you can not have a negative what |-3|+|9| is looking for is the distance from 0 on the X axis since distance can't be negative, (you go 3 miles away from your house in one direction, vs 3 miles in the opposite both ways is positive, even with opposite directions same with axis, it doesnt matter which way, only the number.) you need the absolute value of -3 to get the distance from the 0 on the x axis

short version: distance is positive and its adding the distances from the x axis to get distance from each other
