Not sure how to explain this more, but I hope this helps!
Step-by-step explanation:
step 1. (-0.4)(0.16) = -0.064
step 2. (0.625)(-0.08) = -0.05
step 3. -1.2(-5.1) = -6.12
Answer:
7a........they are similar because none of the sides are equal
Just use the Pythagorean Theorem
(9 +x)^2 = 15^2 + x^2
x^2 + 18x + 81 = 225 + x^2
18x = 144
x = 8
So the three sides of the triangle are
15, 8 and 17
If x=2, the line is just a straight, vertical line intersecting the x-axis at 2.
