Answer:
D. -1.2(3x-40)
Step-by-step explanation:
Multiply -1.2 x 3x and -1.2 x -40.
-1.2 x 3x= -3.6x
-1.2 x -40= 48 (two negatives cancel each other out, so it will be +48)
= -3.6 +48.
You can also automatically eliminate B. and C. because multiplying the -4 within the perenthesis would not give you 48.
A. says (3x + 40), which would give us a negative 48.
Answer:4. BC DE
6. plane t
Step-by-step explanation:
The standard deviation is 2.2
Answer:
See below
Step-by-step explanation:
cos (180 + x) = - cos x
sin (360 + x) = sin x
sin 360 - x) = -sin x
cos (180 - x) = - cos x
3cos (180° + x)sin (360° - X) = -3cos x (- sin x) = 3 cosx sinx
sin (360° + x)cos (180° - x) = sin x (- cos x) = -sinx cosx
3cos (180° + x)sin (360° - X)sin (360° + x)cos (180° - x)
= 3 cosx sinx (-sinx cosx) = -3 (sin x)^2 (cos x)^2
I am not sure what the question really is, but hopefully the above can steer you in the right direction.
Answer:
20
Step-by-step explanation:
We know that the interior angle measures of a triangle are <u>180,</u> and we are told that this is a <u>right</u> triangle.
Since we know the measure of two angles, we just have to do basic math:
180=90+70+x
solve for x (which equals 20) to get the measure of your acute angle
