Answer:
a. Of all the students, 
are girls with blond hair.
b. Of all the students, are boys without brown hair.
Step-by-step explanation:
a. You know that 
of the students are girls (This means that 
of the studes are boys) and 
of these girls have blond hair.
Then, of is:
Therefore, of all the students, are girls with blond hair.
b. You know that 
of the boys have brown hair.
Then, of is:
Of all the students, are boys without brown hair.
<u>Part A</u>
If the number is n, then the expression is 7n+6.
<u>Part B</u>
Three times the sum of a number and 8.
If the graph is a straight line, then it is linear. And If the y values is the same. The power of each, x and y in the equation is one.
The equation for which square method is possible is x²-8=1
Step-by-step explanation:
For checking which of the equation satisfies the complete square condition, we proceed by checking each of the available options
1). x²+20x=52
Rewriting it as x²+20x-52
This binomial expression is not a perfect square since the product of the coefficient of x²(i.e. 1) and independent constant (i.e. 52) is not a perfect square.
2). 5x² + 3x = 9
This equation can be rearranged as 5x²+3x-9=0
This binomial expression is not a perfect square since the product of the coefficient of x²(i.e. 5) and independent constant(i.e. 9) is not a perfect square.
3.) x² −8=1
This equation can be rearranged as x²=9
Hence x= ±3
This binomial expression is a perfect square and can be done by the square method.
4). 3x² −x+17=0
This binomial expression is not a perfect square since the product of the coefficient of x²(i.e. 3) and independent constant(i.e. 17) is not a perfect square.
