Given A(8,3), B(4,8), C(4,4) and D(8,-1) find the slope of AB
Snezhnost [94]

Answer:

Step-by-step explanation:

Slope: \frac{y_2-y_1}{x_2-x_1} when the given points are (x_1,y_1) and (x_2,y_2)

Plug in A(8,3) and B(4,8)

=\frac{8-3}{4-8} \\=\frac{5}{-4}\\=-\frac{5}{4}

Therefore, the slope of AB is -\frac{5}{4}.

I hope this helps!

I give 20! Find the surface area. And without explanation please, I don’t have enough time.
oee [108]

Answer:

816 cm²

Step-by-step explanation:

Surface area of the composite figure = (surface area of the larger rectangular prism + surface area of the smaller rectangular prism) - area of the side of the smaller rectangular prism that is joined to the bigger prism.

✔️Surface area of the larger rectangular prism:

Area = L*W*H = 20*5*6 = 600 cm²

✔️surface area of the smaller rectangular prism:

Area = L*W*H = 12*4*6 = 288 cm²

✔️area of the side of the smaller rectangular prism that is joined to the bigger prism.

Area = L*W = 12*6 = 72 cm²

Surface area of the composite = (600 + 288) - 72 = 888 - 72 = 816 cm².
