Answer:
a)
Step-by-step explanation:
<u>Given: Step 3</u>
(JK)² = LK · MK and (LJ)² = LK · ML
<u>Step 4</u>
Addition property of equality
(JK)² + (LJ)² = LK · MK + LK · ML
<u>Step 5</u>
Distributive property
(JK)² + (LJ)² = LK (MK + ML)

90°
Step-by-step explanation:
right angle - 90°
.....
Answer:
y = 3x - 5
Step-by-step explanation:
The equation of a line parallel to y=3x+6 has exactly the same form but a different constant on the right: y=3x+C
To find C, take the coordinates of the given point and substitute them into y=3x+C:
7 = 3(4) + C, or
7 = 12 + C, and so C = -5
The desired equation is y = 3x - 5
Answer:
(X - 4)(x - 4)
Step-by-step explanation:
x2 - 8x + 16
What two numbers multiply to 16 and add to -8
-4 * -4 = 16
-4 +-4 = -8
(x-4) (x-4)
(x-4)^2
