To subtract fractions, let's put a generic example.
Be the fractions
(a / b) - (c / d)
With a, b, c and d other than zero.
The subtraction of fractions is given by:
(a / b) - (c / d) = ((a * d) - (c * b)) / (b * d).
If the fractions have the same denominator then the subtraction is
(a / b) - (c / b) = (a-c) / (b)
answer
(a / b) - (c / d) = ((a * d) - (c * b)) / (b * d)
(a / b) - (c / b) = (a-c) / (b)
Answer:
For sure 34
Step-by-step explanation:
the red lines are the same length to each letter just add those.
P=2(L+W) and P=34 so
2(L+W)=34
L+W=17 so we can say
L=17-W
A=LW using L from above
A=(17-W)W
A=17W-W^2 and A=30 so
30=17W-W^2
W^2-17W+30=0
W^2-2W-15W+30=0
W(W-2)-15(W-2)=0
(W-15)(W-2)=0
So the dimensions of the rectangle are 15 meters by 2 meters.
To solve this problem you must apply the proccedure shown below:
1. You have that:
- The <span>kite is located at point 25 ft above the ground.
- The kite rises to a point b, directly above point a.
- The angle of elevation changes from 50º to 65º.
2. Therefore, you have:
25 feet/50°=0.5 feet
x=(0.5 feet)(65°)
x=32.5 feet</span>≈33 feet<span>
3. Then, as you can see, the answer is: 33 feet.</span>
