Add the areas of all the sides of the shape.
A triangle's area: 1/2bh
The two triangles' area=24*9=216
The bottom side: 40*24=960
The two other sides: 30*40=1200
Add everything: 216+960+1200=2376
Answer:
y = x - 9
Step-by-step explanation:
Keep in mind that the lines t and u are perpendicular, which implies that their slopes are negative reciprocals of one another. The negative reciprocal of the slope -1 of line t is +1.
Thus we need to find the equation of line u, knowing that the slope of this line is +1. Starting with the slope-intercept form y = mx + b, we find b:
y = mx + b becomes
-8 = (+1)(-1) + b, or -8 =-1 + b. Then b = -9, and the desired equation is
y = x - 9
Answer:
the leading coefficient of a polynomial is the coefficient of the term with the highest degree of the polynomial
so the answer should be the second one -7+6x+5x^2
