4 0

7x - 4y = -28

3x +4y = -12

Using the elimination method because y is already eliminated

10x = -40

So x = -4

Then plug the -4 into the first equation....

7(-4) - 4y = -28

-28 - 4y = -28

-4y = 0

y = 0

I got:  -4,0

An abstract sculpture in the form of a triangle has a base 21 meters and a height of 12 meters. Find the are of the triangle.
charle [14.2K]
The area of a triangle could be determined using the following formula
\boxed{a= \frac{1}{2} \times b \times h}

plug in the numbers
a =  \frac{1}{2} \times 21 \times 12
a =  \frac{1}{2} \times 252
a= \frac{252}{2}
a = 126

The area of the triangle is 126 square meters
