Answer:
cos²x.sec²x =1 (formula)
cos and sec are reciprocal to each other
cos²x=1/sec²x
now from the eq above,open the brackets and multiply
1-cos²2x
sin²2x
The perimeter doesn't tell you the area, and neither of them
can be calculated by knowing the other one.
Check this out:
Dimensions Perimeter Area .
1 by 38 78 38 square feet
2 by 37 78 74 square feet
3 by 36 78 108 square feet
5 by 34 78 170 square feet
10 by 29 78 290 square feet
15 by 24 78 360 square feet
17 by 22 78 374 square feet
19 by 20 78 380 square feet
19.5 by 19.5 78 380.25 square feet
Nine same perimeters, nine different areas !
Here's one more ... a long skinny one:
1 inch by 38ft 11in Perimeter = 78 ft. Area = 3.24 square feet.

Answer:
The Answer is B 8+ 6=14
Step-by-step explanation:
14-8=6
8+6=14
14-6=8
Answer: -7/9
Step-by-step explanation: To identify the slope of this line, first notice that this equation is in standard form which is Ax + By = C.
To find the slope, we need to solve for our variable <em>y</em>.
We first need to identify what is happening to our variable <em>y</em>. You can notice that it's being multiplied by 9 and is being added by 7x because 7x is a +7x so we're adding the 7x to the 9y.
So the first thing we do is undo addition and subtraction to our variable.
On the left the -7x's cancel and we are left with 9y. on the right, we do not want to write 45 - 7x because we always want to keep our variable in front of our constant. So I will just write that as 9y = -7x + 45.
Now we can divide everything by 9 in order to get <em>y</em> by itself.
This leaves us with <em>y = -7/9x + 5</em>.
Now our slope is the multiplier or the coefficient of the <em>x</em> term which in this case is -7/9. So the slope is -7/9.
