Answer:
x = 27
Step-by-step explanation:
3x-4y = 65
Let y = 4
3x - 4*4 = 65
3x -16 = 65
Add 16 to each side
3x-16+16 = 65+16
3x = 81
Divide each side by 3
3x/3 = 81/3
x = 27
For question 4, it would be a^2+b^2=c^2. So you would set up the equation as a^2+14^2=18^2. the third side would equal approximately 23cm.

FGJLPQR Are some letters with no rotational or line symmetry
The area of the rectangle is length times width, that is
A = L*W
The problem requires the width so
W = A/L
Given that A = 437 sq. cm and L = 19 cm, therefore
W = 437/19 = 23 cm
That is the answer.
