Answer:
use the pythagoras theorem ok for 3rd side
i.e. (5.6)²+(3.9)²=c²
Answer:
left 2 and 8
right 2 and 4
Step-by-step explanation:
For each equation at the top you substitute the number into x for the numbers on the left
y=2(1)^2
y=2
y=2(2)^2
y=8
y=2^1
y=2
y=2^2
y=4
Answer:
here,x=123, is the answer.
-4.75= z/2
Multiply both sides by 2
-4.75(2)= z/2(2)
Cross out 2 and 2, divide by 1 and becomes z
z=-9.5
Answer: z= -9.5
