Answer:
yes; 1.25
Step-by-step explanation:
The length to width ratios of the rectangles are ...
A: 12/8 = 1.5
B: 15/10 = 1.5
C: 30/15 = 2.0
__
Rectangles A and B have the same aspect ratio, so are similar. Rectangle B is a scaled copy of A with a scale factor of 10/8 = 1.25.
The answer is C.
The definition of a "quadratic equation" is any equation that has a variable with an unknown value to a power no less than or more than 2. A is not the answer because nothing is to the 2nd power. B, although is to the second power, is simplified into just 4, so it has neither an unknown variable nor power of 2. D is also incorrect because when the 3 is distributed, the equation is just simply 12-3x, which has no power of 2. So C is correct because when the 7x is distributed, you get the equation 7x^2 +21x, which has both a variable with an unknown value and a power of two.

Step-by-step explanation:
Answer:
60°
Step-by-step explanation:
All the sides are of equal length, 12,12,12 , 60,60, ?, so it is 60
First, you need to know the coordinates of the points:
If x is 9 stacked bins to the y of 41 inches, the first point is (9,41)
From there, you can determine the other point: (4,26)
Find the slope by subtraction using the formula: y2-y1/x2-x1
(41-26)/(9-4)
15/5
slope is 3
y=3x+b
To find b, substitute one point into the equation. I will use (4,26)
26=3(4)+b
26=12+b
-12 -12
b=14
Your final equation is:
y=3x + 14
