A square has a side length of 3x +4 units. A second square has a side length that is 2 times the side length of the first square. What is the area of the second square? A. 27x2 + 72x + 54
B. 36x2 + 96x + 64
C. 18x2 + 48x + 32
D. 9x2 + 24x + 16

answer: 0.64

do you have an easier question cause this shh is hard like theheck

step-by-step explanation:

7.9m and 4.3°

step-by-step explanation:

let east be +x and north be +y, x = distance * cos θ, y = distance * sin θ  

for 3.5 south, y = -3.5  

for 8.2, x = 8.2 * cos 30 and y = 8.2 * sin 30  

for 15 west, x = -15  

total x = 8.2 * cos 30 – 15 ≈ -7.9  

total y = -3.5 + 8.2 * sin 30 = 0.6  

magnitude = [(8.2 * cos 30 – 15)^2 + 0.6^2)]^0.5  

the magnitude is approximately 7.9 m  

tan θ = y/x = 0.6/-7.9  

the angle is approximately 4.3˚ north of west
