Answer and Step-by-step explanation:
1. A goat?
2.
So, the first triangle has a side length of 6 and x, and the bigger triangle has a side length of 10 and 11.
We divide 10 by 6 to find the scale factor, then divide 11 by that number.
10 ÷ 6 =
= x
<u>So, the answer is B. 6.6 because 33 divided by 5 is 6.6 (the value of x).</u>

Answer:
x=3, y=15. (3, 15).
Step-by-step explanation:
x+y=18
y=3x+6
----------
x+(3x+6)=18
x+3x+6=18
4x+6=18
4x=18-6
4x=12
x=12/4
x=3
3+y=18
y=18-3
y=15
Answer:
Width = 3 feet
Length = 7 feet
Step-by-step explanation:
x represents the width of doghouse so,
Width = x
Length is 4 times more than its width
Length = x+4
Area of doghouse = 21 square feet
We know
Area of rectangle = Length * Width
21 = (x+4)*x
21 = x^2+4x
=> x^2+4x-21=0
Solving the above quadratic equation by factorization to find the value of x
x^2+7x-3x-21=0
x(x+7)-3(x+7)=0
(x+7)(x-3)=0
x+7 =0 and x-3=0
x= -7 and x =3
Since the width of rectangle can never be negative so, x=3
Width =x = 3 feet
Length = x+4 = 3+4 = 7 feet
