Answer:
AB= 12.94ft, 108deg
ZY= 6.76ft 50deg
XY 3.05ft, 22deg
Pathway adds up to 22.95ft
Step-by-step explanation:
AB is base
Sides 8 feet each = isosceles. =8ft, 8ft, 12.94ft
Top angle is 36 degree = 36°.36°,108°
ZY is base
Sides 8 feet each = isosceles = 8ft, 8ft, 6.76ft
Top angle is 65° = 65° 65° 50 °
XY is base
Sides 8 feet each =isosceles =8ft, 8ft, 3.05ft
Top angle is 79° degree = 79°,79 °,22 °
Pathway means triangles in a row side by side = Product of 3 values = ? feet
12.94 +6.76 + 3.05 =22.95ft pathway
Short answer: C
Let's start with the pen.
The length is x
The width is 3 more.= x + 3
Perimeter of the pen = 2L + 2W
P = 2 L + 2W
P = 2*x + 2(x + 3)
P = 2x + 2x + 6
P = 4x + 6. Leave that for now.
Area of the pen without the doghouse = x(x + 3)
Area of the pen without the doghouse = x^2 + 3x
Area with the doghouse x^2 + 3x - y = 178 (that's his running around space.
Go to the dog house for a Moment
The perimeter of the doghouse and the area are equal and we are told to make them both y.
Area = y
Perimeter = y
Combined facts.
The perimeter of the Pen is three times larger than that of the dog house.
4x + 6 = 3y
The area of the Pen - The area of the doghouse = 178
x^2 + 3x - y = 178
Now what happens is that you have to juggle these two equations so they look like your answer
x^2 + 3x - y = 178
4x + 6 = 3y Subtract 3y from both sides.
4x - 3y + 6 = 0 Subtract 6 from both sides.
4x - 3y = - 6
Answer C
Answer:
If x is greater than 1 it is growth, if it less than it is decay
