For the triangle, the shaded part, both the height and base are 12, so the area of it is:
1/2 (12 x 12) = 72
And the area of the whole square is 144
But what we’re looking for is the area of the unshaded region. So to find it, we’ll need to subtract the shaded from the total. So:
144 - 72 = 72
Thus, the area of the unshaded region is 72

Answer:
14
Step-by-step explanation:
(a+b)^2
(a+b)(a+b)
FOIL
a^2 + ab+ab + b^2
Combine like terms
a^2 +2ab + b^2
Rearranging
a^2+b^2 +2ab
We know a^2+b^2 = 4 and ab= 5
4 + 2(5)
4+10

Answer:
slope = -1 or -x
Step-by-step explanation:
Do y2-y1/x2-x1
Plug in
-1 - 4/ 2 - -3 = -5/5
(Simplify)
-1 so the slope is
-1 or -x
If you want to find the equation use one of the points you have.
4 = -1(-3) + b
4 = 3 + b (subtract 3 on each side)
1 = b
y = -1x + 1 is the equation
he would have traveled 210 miles because in half an hour he would have traveled 30 miles and in 3 hours he would have traveled 180 miles. so we have to add those up and we get our answer: 210 miles
