Answer:-4(2x-5)
Step-by-step explanation:
-4(2x-5)
-4(2x)+(-4)(-5)
-8x+20
-8/-4x+20/-4
-4(2x-5)
18 divided by 30 is 0.6. So I would say that B, or 0.6, is the correct answer.
This will help a lot if you go to desmos! Just graph the equation on there! It’s much easier to see on computer
Assuming that the triangles are congruent, you can just look at the parts on each triangle to find the parts on the other triangle. The answers are yes, yes, and no. The triangles are obviously not drawn to scale, so just remember to never rely on it being so.
Answer:
TSA = 175.84 ft²
Step-by-step explanation:
We are given;
Lateral surface area; A_L = 75.36 ft²
Area of base; A_b = 50.24 ft²
Height of cylinder; h = 3ft
Formula for total surface area of Cylinder is;
TSA = 2πr² + 2πrh
Now, lateral surface area is given by the formula; A_L = 2πrh
Area of base is given by the formula;
A_b = πr²
Thus, let's apply these 2 formulas to the formula for total surface area;
TSA = 2(Area of base) + Lateral surface area
TSA = (2 * 50.24) + 75.36
TSA = 175.84 ft²
