Number 1:

9x^2 + 12x + 4 -> (3x + 2)^2
16x^2 + 24x + 9 -> (4x + 3)^2

2. x^2 + Bx + 64
B = (sqrt64) *2 = 16

3.
Solving equations like this requires completing the square, which has the first step of choice 4.

Evaluate the integral: dx / e^(pie*x) from 2 (upper bound) to 0.

kenny6666 [7]

Substitution:
u = - π x
d u = - π d x
d x = - d u / π
----------------------
$-1/ \pi \int\limits^2_0 {e ^{u} } \, du =- \frac{e ^{- \pi x} }{ \pi } = \\ -1/ \pi (e ^{-2 \pi } -1) = \\ = \frac{1}{ \pi } - \frac{1}{ \pi e ^{2 \pi } }$

Answer:

C-D = 6

A-B = 3.25

D = 118

Step-by-step explanation:

C-D = 6 because the line is the same as B-C

A-B = 3.25 because the line is the same as A-D

D = 118 because the angle of B is vertically opposite to D
