-24+m=-47
First, you add 24 to -47. Then you find that m=-23. To check your work, plug -23 in the equation for m, and solve.
Answer:
x = 9
Step-by-step explanation:
The triangle is split into two similar triangles. They have the same shape but not the same size. To solve, write a proportion.
Cross multiply to solve for x.
9(3x+36) = 81(3x-20)
27x + 324 = 243x -1,620
1,944 = 216x
9 = x
I think you should write the equation to find perimeter such as P = 2(L + W). So the expression is 2[2(x+y) + 3(x - y)]
Simplified as 2[(2x + 2y + 3x - 3y)]
2(5x - 1y) combined like terms
10x - 2y is the expression for the perimeter of the rectangle
Answer:
The answer would be C.) 2.12
Step-by-step explanation:
according to the drawing, the minimum value of the function is 0, the domain of the function decreasing is x < 0,
so, the correct answer is
a. (-oo, 0)
