Represent the shorter sides as  x and the longer side as x + 5You know the Perimeter has to equal the sum of all three sides which is 29.So the equation to solve for x is 29 = x + x + (x + 5)
Each x is a shorter side and the 5+x is the long side. so then just solve for x.29 = 3x + 5 subtract 5 from each side29 - 5 = 3x24 = 3x then divide each side by 324/3 = x8 = x x equals 8 so each short side is 8m long. to get the length of the long side add 5+8=13m

PLZ ANSWER THIS I CANT FIGURE OUT THE SECOND ONE
mihalych1998 [28]

Answer:

Step-by-step explanation:

The first one is actually 0 I think. The instantaneous ROC at x=1 should also be 0. The last one should be correct.

Basically, the ROC for the first one is 0 because the y value at the start and end of the interval is the same, so the change is the same. However, for the instantaneous ROC at x = 0, you look at the graph and realize that if you find the derivative at that point, it is 0.

Can someone please help with this question pleaseee
Ulleksa [173]

Answer: Choice C) 10.5

The distance from A to C is 7 units (count out the spaces between the two points, or subtract y coordinates 4-(-3) = 4+3 = 7)

Let AC = 7 be the base of the triangle. You might want to rotate the image so that AC is laying horizontally rather than being vertical.

Now move to point P. Walk 3 spaces to the right until you land on segment AC. This shows that the height of the triangle is 3 when the base is AC = 7.

base = 7, height = 3

area of triangle = (1/2)*base*height

area of triangle = 0.5*7*3

area of triangle = 10.5 square units
