Answer:
![\frac{1}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B4%7D)
Step-by-step explanation:
=
We need a common denominator before we can add.
+
means the same thing as
-
= ![\frac{1}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B4%7D)
Answer:
12) 5.96 ; 13)
Step-by-step explanation:
12). x and 5 are legs, so
opposite leg/adjacent leg = tangent 40°
5/x= tan40°, 5= x*tan40°, x= 5/tan40° ≈ 5.96
13). 15 is opposite leg
24 is hypotenuse
opposite leg/hypotenuse = sin(x)
sin(x) = 15/24
x = arcsin(15/24) ≈ 38.68°
Perpendicular lines, slope is opposite and reciprocal
so slope of new line = - 4
passes through (-2, -6) in point-slope form
y + 6 = -4(x + 2)
Answer is C. y + 6 = -4 (x + 2)
The correct answer is C, if you use the distributive property and multiply all of them by each other you would get x^3+2x^2+3x+6.
Hope this helps :-)
