Answer:
a² + 16a - 612 = 0
Step-by-step explanation:
Here is the complete question :
The width of an extra large rectangle poster is 8 inches more than half its length. The area of this poster is 306 square inches
Write an equation in one variable that could be used to find the number of inches in the dimensions of this poster.
Area of a rectangle = length x width
Let length = a
width = 8 + 1/2a
Area = (8 + 1/2a) x a
306 = (8 + 1/2a) x a
multiply both sides of the equation by 2
612 = 16a + a²
a² + 16a - 612 = 0
the dimensions of the poster can be determined using quadratic formula
Answer:
The anwers Is C and E.
Step-by-step explanation:
A relationship between two quantities is proportional if the ratio between those quantities is always equivalent.
Hint #22 / 4
Let's look at the ratio between right- and left-handed students at East Middle School.

10.5 right-handed students for every left-handed student.
Hint #33 / 4
Now we can compare the other combinations of values for left-handed and right-handed students. Which ratios are equivalent to the ratio at East Middle School?
So the anwers is C AND E
C is the answer 10 because 10 is the answer 10 is the number that was repeated the most so its the mode
Answer:
y-intercept = -1
Step-by-step explanation:
Answer:
C
Step-by-step explanation:
It is a function because it passes the vertical line test and Xs do not repeat, then count out the Y-values which are the range.
