Use Pythagaras theorem :-
x^2 = 1.8^2 + 2.4^2 where a is distance required
x^2 = 9
x = 3 miles Answer
P=2*(L+l)=46
L+l=46:2
L+l=23
(L+l)^2=529
(L^2+l^2)+2l*L=529
D= V L^2+l^2= 17
L^2+l^2=289
so 289+2l*L=529
2l*L=529-289=240
l*L=240:2
A=120
Step-by-step explanation:
The point-slope form of an equation of a line:

m - slope
We ahve the slope m = 1/2 and the point (-2, 1). Substitute:

- point-slope form
Covert to the slope-intercept form (y = mx + b):
<em>use the distributive property</em>
<em>add 1 to both sides</em>
- slope-intercept form
Convert to the standard form (Ax + By = C):
<em>multiply both sides by 2</em>
<em>subtract x from both sides</em>
<em>change the signs</em>
- standard form
Convert to the general form (Ax+By+C=0):
<em>add 4 to both sides</em>
- general form
Answer:
2k + 80
Step-by-step explanation:
Combine like terms.
3k + 8 - k + 72 =
= 3k - k + 8 + 72
= 2k + 80
