The answer is B 803.8cm^2
Answer:
See explanation
Step-by-step explanation:
sin(α + β) = sin α cos β + sin β cos α
sin(α - β) = sin α cos β - sin β cos α
[ sin(α + β) + sin(α - β)] = [sin α cos β + sin β cos α + sin α cos β - sin β cos α]
= [2 sinα cos β]
= sin α cos β = [ sin(α + β) + sin(α - β)]
Answer:
Step-by-step explanation:
1. Symbolically, we get: 62 - 5x < 40
2. y - 7.3 < 3.4. Solve for y by adding 7.3 to both sides, obtaining:
y < 10.7 This is both the 'range' and the 'solution'
3a) 4b = 9b + 45, or -5b = 45, or b = -9
3b) 5a + 10 = 4a - 4
Combining like terms results in a = -14
10ft by 12ft = 120
12ft by 12 ft = 144
144-120 = 24 sq ft
You need 24 square feet.
I Agree because everything has to come with lines because every thing has to come in a shape with lines
