Answer:
C. -3, 6, -9, -1
Step-by-step explanation:
A coefficient is a number used to multiply a variable.
Example: 6z means 6 times z, and "z" is a variable, so 6 is a coefficient.
Variables with no number have a coefficient of 1.
Example: -x is really -1x.
Multiply 575 by .16
Multiply 750 by 1.02
25% is 1/4 of 100% so multiply 80 by 4.
Answer:
No, this is not a strong evidence that the parameter has changed since 2018. This is because, there are so many factors that could have led to the fall in percentage of "disadvantaged school students" from the initial 3.5% to 4.3%.
Some of the factors could be reduction in the number of disadvantaged students, sample size considered being considered as well as the geographic location upon which the random sampling was made.

Answer:
h=55.4 mm
Step-by-step explanation:
Area of a triangle =
where b is base and h is height
now just plug and chug
227.14 = 8.2h/2
227.14=4.1h
h=227.14/4.1
h=55.4
check answer:
55.4 * 8.2 /2 = 227.14, as proven by my calculator
First, you distribute the 3 into the brackets,
<span>3(x - 2) + 5x
=</span><span>3(x) + 3(-2) + 5x
=3x - 6 + 5x
Adding the like terms, 3x and 5x, gives you
=8x - 6</span>
