Option A: -4/9x-4 is the correct answer
Answer:
The expression (11.9f + 6.7g + 8.2h) cm represent the perimeter of the triangle
Step-by-step explanation:
Perimeter of a triangle = side a + side b + side c
Side a = (8.3f + 9.6g)
Side b = (3.6f + 1.5h)
Side c = (6.7h - 2.9g)
Perimeter of a triangle = side a + side b + side c
= (8.3f + 9.6g) + (3.6f + 1.5h) + (6.7h - 2.9g)
= 8.3f + 9.6g + 3.6f + 1.5h + 6.7h - 2.9g
Collect like terms
= 8.3f + 3.6f + 9.6g - 2.9g + 1.5h + 6.7h
= 11.9f + 6.7g + 8.2h
Perimeter of a triangle = (11.9f + 6.7g + 8.2h) cm
The expression (11.9f + 6.7g + 8.2h) cm represent the perimeter of the triangle
Answer:
(-2,0)
Step-by-step explanation:
intercepts at (-2,0) horizontally. look at the graph
15 minutes is one quarter of an hour, so the number of people accommodated in an hour would be 4 x 55 = 220 people per hour
Hi there!
So, let’s start with the rectangles. You would multiply 4(2 ft x 3 ft) since length x width = area (for rectangles). You multiply by 4 because there are 4 rectangles mentioned, and each have the same 2 ft x 3 ft measurements.
Next, you multiply 2(2 ft x 2 ft), or 2 to the exponent of 3, i.e., 2^3. 2 ft x 2 ft are the measurements of the sides of the squares, and as you probably know, side x side OR side^2 = area (for squares). Again, you multiply the original 2 ft x 2ft area by 2 because there are 2 squares mentioned with the same 2 ft x 2 ft measurements.
Finally, you add 4(2 ft x 3 ft) and 2(2 ft x 2 ft) together to equal the total area of plywood purchased, or the total amount of square feet of plywood he is purchasing in all.
