a linear equation is proportional..this is the answer I think..
Answer:
There is no drawing we will not be able to answer your question.
Step-by-step explanation:
Answer: 500m
Explanation:
If the scale of the drawing is 1:500 then the real playground should be 500:1 which is 500m
The formula of an area of a rectangle:
A = wl
We have l = w - 4 and A = 21.
Substitute:
w(w - 4) = 21 <em>use distributive property</em>
(w)(w) + (w)(-4) = 21
w² - 4w = 21 <em>subtract 21 from both sides</em>
w² - 4w - 21 = 0
w² - 7w + 3w - 21 = 0
w(w - 7) + 3(w - 7) = 0
(w - 7)(w + 3) = 0 ↔ w - 7 = 0 ∨ w + 3 = 0
w = 7 ∨ w = -3 < 0
l = w - 4 → l = 7 - 4 = 3
<h3>Answer: the length = 3 u.</h3>
Answer:
![\sqrt{61}](https://tex.z-dn.net/?f=%5Csqrt%7B61%7D)
Step-by-step explanation:
To find the distance, we first do B - A, where B is (-6, 7) and A is (-1, 1):
(-6, 7) - (-1, 1) = (-6+1, 7-1) = (-5, 6)
Imagine it as a triangle, where the hypotenuse is the distance, and -5 and 6 are the lengths of the sides.
To find the hypotenuse (Pythagorean Theorem): ![\sqrt{(-5)^2+6^2} =\sqrt{25+36} =\sqrt{61}](https://tex.z-dn.net/?f=%5Csqrt%7B%28-5%29%5E2%2B6%5E2%7D%20%3D%5Csqrt%7B25%2B36%7D%20%3D%5Csqrt%7B61%7D)
The answer is the square root of 61.
