Answer:
w=7 and l=10
Step-by-step explanation:
To find the dimensions, create an equation for its perimeter and solve. Recall, the perimeter formula for a rectangle is P = 2l+2w. P is 34 cm. L is 4cm less than twice the width or 2w-4. And the width is w.
P = 2l+2w
34 = 2(2w-4) + 2w
34 = 4w -8 +2w
34 = 6w -8
34+8 = 6w
42 = 6w
7=w
The width is 7 cm. To find the length substitute w=7 into l=2w-4.
l=2w-4
l=2(7)-4
l=14-4
l=10
Answer:
fourth option
Step-by-step explanation:
Using the trigonometric identity
cos²x + sin²x = 1
Divide all terms by cos²x
+ 
= 
which gives
1 + tan²x = sec²x
Answer:
Perpendicular lines form 90 degree angles. It creates 4 of them, to be exact. Hope this helps! :)
Answer:
Ethan started of with 246,000 Twitter followers
Step-by-step explanation: 12,000 x 4 = 48,000
48,000 + 198,000 = 246,000
138 because 92/4 equals 23 which is the miles per gallon, then you multiply that by 6<span />
