If you're behind like I am and are just now doing these assignments then good luck on catching up.
If it's AQRB Unit 2 Lesson 3 then the answers to the multiple choice are below, you'll need to do the essay and calculation on your own.
1: $674.64
2: $26, 255.38
3: $191, 398.49
4: $23, 884.84
Answer:
R = (- 3.5, - 7 )
Step-by-step explanation:
Using the Section formula
= 
= 
= 
= - 3.5
= 
= 
= 
= - 7
Thus coordinates of R = (- 3.5, - 7 )
Area of trapezoid : (Base 1 + base 2) x h x 1/2
Let's solve!
( 2+6) x 5 X1/2
= 40x1/2
=20
20 in squared is the area!
8t+32 is one expression equivalent to that.
2x^2 + 3xy - 4y^2 when x = 2 and y = -4
= 2(2)^2 + 3(2)(-4) - 4(-4)^2 = 2(4) + (-24) - 4(16) = 8 - 24 - 64 = -80
