Answer:
4) x = - 12
5) x = 4
Step-by-step explanation:
4)
Since points T and S are mid points of sides ML and MN of triangle MLN.
Therefore, by mid point theorem,
TS is half of LN
so,
5) In the same way x = 4 will be the correct answer in question number 5.
Answer:width is 9ft
Length is 12 ft
Step-by-step explanation:
Let L represent the length of the rectangle.
Let W represent the width of the rectangle.
The area of a triangle is expressed as length, L × Width, W.
Area of the rectangular pen is 108 ft^2. Therefore,
LW = 108 - - - - - - - 1
if the width is 3 feet less than the length, it means that
W = L - 3
Substituting W = L - 3 into equation 1, it becomes
L(L - 3) = 108
L^2 - 3L = 108
L^2 - 3L- 108 = 0
L^2 + 9L- 12L - 108 = 0
L(L + 9) - 12(L + 9) = 0
L - 12 = 0 or L + 9= 0
L = 12 or L = - 9
The length cannot be negative,
so Length = 12ft
W = 108/L = 108/12 = 9 ft
It seems as though x would be the same, because it’s a 90 degree angle cut in half
I know the 1st and last one but i’m not sure on the rest sorry :(
11+5=16
Because he is 5 years under half
16 multiplied by 2 is 32
