Answer:
the answer is 2 you add one and the other one and it makes 2
Step-by-step explanation:
I have a feeling, these were the answer choices you were trying to make: <span>A ∪ B = {7}
B ⊆ B
B ⊂ A Also, the second answer is the only one that's true

A trapezoid/trapezium is a quadrilateral (4 sided shape) with exactly one pair of parallel sides.
It is a quadrilateral (a closed plane shape with four linear sides) that has at least one pair of parallel lines for sides
Answer: (a) e ^ -3x (b)e^-3x
Step-by-step explanation:
I suggest the equation is:
d/dx[integral (e^-3t) dt
First we integrate e^-3tdt
Integral(e ^ -3t dt) as shown in attachment and then we differentiate the result as shown in the attachment.
(b) to differentiate the integral let x = t, and substitute into the expression.
Therefore dx = dt
Hence, d/dx[integral (e ^-3x dx)] = e^-3x
