A right angle is an angle with a measure of 90 degrees.
Distance formula : d = sqrt (x2 - x1)^2 + (y2 - y1)^2
(-5,-1)(-1,12)
d = sqrt (-1-(-5)^2 + (12 - (-1)^2
d = sqrt (-1 + 5)^2 + (12 + 1)^2
d = sqrt (4^2) + (13^2)
d = sqrt (16 + 169)
d = sqrt 185
d = 13.60 <==

Answer:
- 40
Step-by-step explanation:
When a = 4, and x = -4:
Evaluating algebraic expressions simply involve substituting the given values for <em>a</em> and<em> x</em> into the expression, -9a + x.
Hence, -9a + x = -9(4) + (-4) = -36 - 4 = -40
Therefore, the correct answer is -40.
The answer to this question is :
Part A
((3x+7)+(4x-2))x
(3x+7)+(4x-2): 7x+5
x(7x+5)
Part B
((3x+7)*(4x-2))x
x(12x²+22x-14)
12x³+22x²-14x
Part C
(3x+7)[4x-2(x)]
4x-2(x)
4x-2x
2x
2x(3x+7)
