Answer:
Step-by-step explanation:
The identity you will use is:
So,
Now, using the difference of sin
Note: state that
Solving the difference of sin:
Then,
Once
And,
Therefore,
Y = mx + b....m is the slope and b is the y intercept
slope(m) = 5...(4,0)...x = 4 and y = 0
now we sub our info into y = mx + b...we r looking for b, the y intercept
0 = 5(4) + b
0 = 20 + b
-20 = b
so ur equation is y = 20x - 20...but we need it in standard form
Ax + By = C
y = 20x - 20....subtract 20x from both sides
-20x + y = -20...multiply by -1 to make x positive
20x - y = 20 <== standard form
Width of smaller tv=x. in feet
length of smaller tv =x+1
l of larger= x+1.5
w of larger = x +0.5
area = l x w
area = (x+1.5)(x+ 0.5)
area= x^2 +2x + 0.75
Answer: 60 ft
Separate into 2 rectangles and add their areas together!
Vertical rectangle area: 10 x 3 = 30 ft
Horizontal rectangle area: 10 x 3 = 30 ft
Area of entire thing: 30 + 30 = 60 ft
I think the first one is C
