1 + 1x
OR
1 + x
They mean the same thing! Hope this helps!
Answer:
(3,1) because x is 3 and y is 1.
Step-by-step explanation:
x+2y=5
3x+5y=14
Multiply first equation by 3:
3x+6y=15
3x+5y=14
Subtract 3x:
1y=1
Therefore, y = 1
Plug it back into 1st equation:
x+2(1)=5
x+2=5
Therefore, x = 3
Judging from your answers, it looks like (3,1) because x is 3 and y is 1.
I hope this helped!

Answer:

Step-by-step explanation:
The formula for the area of a triangle is given by :

Where
b is base and h is height
We need to rearrange the formula to solve for height h.
Cross multiply the given relation

Dividing both sides by b.

So, the formula for the height of the triangle is
.
