Answer:
3 ft at each end
Step-by-step explanation:
The lot area is 7 x 5 = 35ft2
The planned lot area = 143ft2
The plan is to extend the lot by equal length on both the width and the length therefore we can express the extension as y the planned lot can be express as
(5+y) x (7+y) = 143
y2 +12y+ 35 = 143
y2 +12y - 108= 0 expand the equation
y2 +18y - 6y -108= 0 factorise the equation
(y-6) (y+18) = 0
(y-6) =0 or (y +18)= 0
y =6. or y = -18
Length can only be a positive number hence y =6
However we need to note that we are increasing the 4 directions a length has 2 end so increasing at both end implies
6/2 = 3 ft at each end
The number of choice out of 7 that consumer have are 42.
<h3>What is permutation?</h3>
The term permutation alludes to a numerical computation of the quantity of ways a specific set can be sorted out. Set forth plainly, a change is a word that depicts the quantity of ways things can be requested or organized. With stages, the request for the course of action matters.
<h3>According to given data:</h3>
Number of choices of side dishes does a customer have,
total dishes(n)=7 , r = 2
ⁿP₂
⁷P₂
7×6 = 42
Thus required number of ways are 42.

Answer:
Step-by-step explanation:
Given
See attachment for triangle
Required
Find x
From the attachment, we have x and 127 on a straight line.
So, we have:
--- angle on a straight line
Subtract 127 from both sides
