Answer:
D
Step-by-step explanation:
Congruent sides mean that they have "EQUAL" lengths.
So, to prove to sides are congruent means that their lengths are equal.
Slope gives the slope of a line. So this can't be it.
Area gives the area of figure. Nothing to do with congruency of 2 lines.
Midpoint formula gives the coordinates of the midpoint. Nothing here.
Distance formula gives the length of sides. So, this is the one we can use to prove that a figure has congruent sides. We can place the figure in coordinate system and find the length of 2 respective sides using "distance formula"
Correct answer is D
Answer:
The answer to your question is w = 1.2
Step-by-step explanation:
Data
Equation 7(w + 2) + 0.5w = 5
Expand 7w + 14 + 0.5w = 5
Simplify like terms (7w + 0.5w) + 14 = 5
7.5w + 14 = 5
Subtract 14 in both sides
7.5w + 14 - 14 = 4 - 15
Simplify
7.5w = - 9
Divide both side by 7.5 7.5/7.5w = 9/7.5
Simplify
w = 1.2
0.4 is 4/10 in decimal form.
