5. Area = 2 unit * 7 units = 14 squared units
6. Area = 3 units * 4 units = 12 square units
7 Area = Area of big rectangle + Area of small rectangle = 42 + 15 = 57
8. Area = 1 * 5 + 2*8 = 5 + 16 = 21 square units
Hope that helps!

Answer:
y=-3x-2
Step-by-step explanation:
step 1- find the slope
parallel to means same slope, so look at y+3x=4, its not in the correct slope form so we subtract both sides by 3x to get y=-3x+4, the slope is the coefficient of x which is -3. Slope equals 3
step 2- use the point slope form which is y-y1=m(x-x1)
and substitute in the numbers (only substitute y1,x1, and m)
m is the slope which we found to equal -3
x1 and y1 are the points that they gave us (-2,4) are (x1,y1)
x1=-2
y1=4
step 3- substitute
y-y1=m(x-x1)
y-4=-3(x-(-2))
simplifies to y-4=-3x-6
add 4 to both sides to get y=-3x-2
There is 180 degrees in a triangle so it is 80 degrees
