100 x 4.2 would equal 420.
The answer is 4.2
Answer:
sinB= 3/5, tanA=4/3, cosB=4/5
Step-by-step explanation:
<h3>Answers:</h3><h3>Area of parallelogram = 63</h3><h3>Area of triangle = 34</h3><h3>Area of trapezoid = 84</h3><h3>The trapezoid has the largest area</h3>
==================================================
Work Shown:
area of parallelogram = base*height
area of parallelogram = 9*7
area of parallelogram = 63
----------
area of triangle = (1/2)*base*height
area of triangle = (1/2)*10*6.8
area of triangle = 34
----------
area of trapezoid = height*(base1+base2)/2
area of trapezoid = 6*(13+15)/2
area of trapezoid = 6*(28)/2
area of trapezoid = 168/2
area of trapezoid = 84
Answer: y = 2x - 20
1. y + 18 = 2(x - 1)
2. y + 18 = 2x - 2
3. y + 20 = 2x
4. y = 2x - 20
10x-7(3x+8)=-26x+4
first you have to isolate the variable
then you divide each side by factores that don't contain the vairable
for this problem if you follow those steps
X=4
-7(3x+8)=-36x+4
-11(3x+8)=-36x+4
