When y=6, then in equation 7y=8x-14 we write 6 instead of y:
7×6=8x-14
42=8x -14
8x-14=42 (now we add 14 to both sides of equation)
8x=56 (now we divide by 8 both sides of equation)
x=7
Answer: x=7
Answer:
5cm
Step-by-step explanation:
Given data
Length= 3cm
Width= 4cm
Applying Pythagoras theorem
z^2= x^2+y^2
z^2= 3^2+ 4^2
z^2= 9+16
z^2= 25
square root both sides
z= √25
z= 5cm
Hence the diagonal is 5cm
Answer: if it’s perimeter the answer is 34 if your looking for area the answer is 55
