Answer:
17285 female doctors
Step-by-step explanation:
We need 31.2% of 55,400 doctors to do this we multiply 31.2% by 55,400
0.312 is 31.2% as a decimal
so we do...
0.312 * 55,400 = number of female doctors
if type that into a calculator you get 17284.8
17.284 rounds to 17285
so the answer is...
17285 female doctors
No because there are no parentheses, therefore no distributive property
An equation that can be used to determine the value of x is x² + 5x - 36 = 0.
To answer the question, we need to know what equations are
<h3>What is an equation?</h3>
An equation is an expression which shows the relationship between two variables.
Given that the x represents the length of side of the square picture and the rectangular sheet poster leaving a border around the picture of 2 inches on the bottom and 1 inch on each remaining sides.
Then,
- The width of the rectangular poster is W = x + 2 + 1 = x + 3.
- The length of the rectangular poster is L = x + 1 + 1 = x + 2
So, the area of the rectangular sheet poster is A = LW
= (x + 2)(x + 3)
Since the rectangular sheet poster has an area of 42 square inches, A = 42 in².
So, (x + 2)(x + 3) = 42
x² + 3x + 2x + 6 = 42
x² + 5x + 6 - 42 = 0
x² + 5x - 36 = 0
So, an equation that can be used to determine the value of x is x² + 5x - 36 = 0.
