Answer:
Step-by-step explanation:
Given

Determine the solution
Since b is a perfect square, the equation can be expressed as:
Apply difference of two squares:
Split:
Remove brackets:
Make a the subject in both equations
The solution can be represented as:
Hello!
(7x²y³)(3x⁵y⁸)
Multiply by ADDING exponents with the same base:
(7 * 3) (x² * x⁵) (y³ * y⁸)
21 * x² ⁺ ⁵ * y³ ⁺ ⁸
Simplify:
21 * x⁷ * y¹¹
21x⁷y¹¹
Answer:
Tyler's - (-5 - 3y) + (3y) = -5
Han's - (x) + (-5 - x) = -5
Step-by-step explanation:
If we are going to use Tyler's first step then we would use x = - 5 - 3y and substitute it in the original simultaneous equation x + 3y = -5, becoming (-5 - 3y) + (3y) = - 5 giving an exact answer of - 5.
But if we are using Han's first step then we will still substitute into the original simultaneous equation but in 3y. It would become
x + (-5 - x) = - 5 which also gives us an exact answer of -5.
Thus proving that both first steps show the same solution of -5.
Answer: 22
Step-by-step explanation:
I’m not sure if hats number is a 5.50 but if it is the answer would be 22 I think ^^ I might be wrong?
Answer:
C. None of the above
Step-by-step explanation:
we know that
The number of students who signed up for different after school activities are
Cooking------------> 9 students
Chess---------------> 4 students
Photography-----> 8 students
Robotics-----------> 11 students
Total of students -----> (9+4+8+11)=32
<u><em>Verify each statement</em></u>
case A) The ratio of photography students to all is 4:1
The statement is false
Because the ratio of photography students to all is 8:32
Simplify
1:4
case B) For every 1 chess student there are a total of 16 students
The statement is false
Because the ratio of chess student to all is 4:32
Simplify
1:8
so
For every 1 chess student there are a total of 8 students
therefore
C. None of the above
