Answer:
x = 2, y = 9 or (2,9)
Step-by-step explanation:
Hello!
The first equation "y = 5x - 1" is telling us that y is equal to 5x - 1
We can plug in the first equation into the second like this:
2x + y = 13 (we know y so we can plug it in)
2x + (5x - 1) = 13
2x + 5x - 1 = 13
7x - 1 = 13
Now we add 1 to both sides
7x - 1 + 1 = 13 + 1
7x = 14
x = 2
Now we plug in x to find y:
y = 5x - 1
y = 5(2) - 1
y = 10 - 1
y = 9

Answer:
x = 18.64
Step-by-step explanation:
use tan:
⇒ tan = 
⇒ tan 46 = 
tan of 46 is 1.0355
⇒ 1.0356 =
multiply 18 on both sides
⇒ 1.0355 x 18 = x 18
⇒ 18.64 = x
The perimeter of the triangle = 15+12+9 = 36 m
Therefore the side of the square must be 9 m longer because 4 * 9 = 36
Answer is B
