Arrange the angles from smallest to largest
First, we need to determine the value of x.
Since, it is a triangle:

Answer:
Length = 27cm
Width = 10cm
Step-by-step explanation:
Let the length of the rectangle be x
Let the width be y
If the length of a rectangle is 7cm more than twice the width, then;
x = 2y + 7
Since P = 2(x+y)
P = 2(2y+7+y)
P = 2(3y+7)
P = 6y+14
If the width is tripled, P = 74
74 = 6y+14
6y = 74-14
6y = 60
y = 10
Since x = 2y+ 7
x = 2(10) + 7
x= 20+7
x = 27
Hence the original dimension is 27cm by 10cm
Answer:
Sugar Maple
8 + 1.5x = 15.5
Fraser Fir
8 + 0.25x = 9.25
Sycamore
8 + 2.5x = 12.5
Oak
8 + 4x = 28
It <u>cannot</u> be <em>Red Maple</em> or <em>Linden</em>, because they are multiplying the number of years by the height it already has. We are looking for the height it <u>will have</u> BASED on the <u>rate</u> that Chang calculated.
Therefore, we are multiplying the <u>RATE</u> by the <u>NUMBER OF YEARS (x)</u>
Step-by-step explanation:
It cannot be red maple, because you are multiplying the height it already has, and not the rate it will grow by. The same goes for Linden.
The right expression to represent the growth of Red Maple would be
8 + 3x = 23
The right expression to represent the growth of Linden would be
8 + 1.5x = 15.5
Therefore, again, the <u>correct answer(s)</u> would be: <u>Sugar Maple, Fraser Fir, Sycamore, and Oak</u>.
