Find the area of the triangle.
NARA [144]

Answer:

16 Unit

Step-by-step explanation:

With P(-2,1) , Q(6,1) , R(4,-3) , S(4,1) ,  the triangle and its altitude look like the one attached in figure.

The length of base PQ is the difference in the x-coordinates of P and Q,

6-(-2)=6+2=8 , because the y-coordinates are both the same as 1.

The height (the length of altitude RS is the difference in the y-coordinates of R and S,

1-(-3)=1+3=4 , because the y-coordinates are both the same as 4 .

The area is

\frac{base*height}{2}=\frac{8*4}{2}=16.

7y - 12 / 5 minus y - 2/3 is equal to 1​
In-s [12.5K]

Answer:

y = 61/90

Step-by-step explanation:

7y - 12/5 - y - 2/3 = 1

Combine like terms.

6y -46/15 = 1

Add 46/15 to both sides.

6y = 61/15

Divide both sides by 6.

y = 61/90
