Find the perimeter of a triangle with sides that measure 2.7km,3.3km,4.3km

10.3 km

Step-by-step explanation:

Perimeter = side1 + side2 + side3

side1  = 2.7 km

side2 = 3.3 km

side3 = 4.3 km

Perimeter = 2.7 + 3.3 + 4.3

Perimeter = 10.3 km

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.

the formula of a slope:

we have the points (-2, 7) and (2, 3). substitute:
