Find the area of a triangle having vertices at (-4,8); (3,-11); and (1,6)

check the picture below.

so, we can simply split that triangle, intwo two triangles, as you see in the picture, the blue and yellow ones.

notice, the blue one has a height of 2, a base of 5, whilst the yellow one has a base of 5 and a height of 17.

now, we can simply get the area area of each triangle, add them up, and that's the area of that larger triangle.

-7

step-by-step explanation:

x^2 + 18x + 74 = (x + 9)^2 - 81 + 74

= (x + 9)^2 - 7.

so q = -7.

7.25

step-by-step explanation:

we know that 7 equals to 7.0. we also know that 1/4=0.25. so we can add the two together and we get 7.25
