Question 9
An isosceles triangle and a square are shown below. If the perimeter of the triangle is 27 more than the
perimeter of the square, find the value of x.
Answers
Answer:
x = 9
Step-by-step explanation:
equation:
3x + 3x + x = x + x + x + x + 27
simplify:
7x = 4x + 27
3x = 27
x = 9

Name the remainder for the quotient and describe or show how you found the remainder.
Answers
Answer:
remainder = 0
Step-by-step explanation:
Using the remainder theorem
If f(x) is divided by (x - h) then the remainder is f(h)
Here f(x) = x³ - x² - 17x - 15 and h = 5 , thus
f(5) = 5³ - 5² - 17(5) - 15 = 125 - 25 - 85 - 15 = 0 ← remainder
Since remainder is zero then (x - 5) is a factor of f(x)
A certain video game console uses 154 watt-hours of energy each hour.
The console used 276 hours last year.
How many watt-hours of energy did the console use?
Use any method to solve this problem. You must show all your work.
Then, explain your reasoning and the steps you took to solve the problem.
Answers
Answer:
42,504 watts
Step-by-step explanation:
154x276hours=42,504watts
Answer:
42504
Step-by-step explanation:
As it uses 154 watt-hours per hour, in 276 hours, it would use 42504 as we would multiply the energy usage by the amount of hours used:
154 watt-hours = 1 hour
276 hours = 42504 watt-hours
276*154 = 42504

Solve: sqrt(x+9) = x-3
Answers
♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️
[tex] \sqrt{x + 9} = x - 3[/tex]
Sides gets power 2
[tex] ({ \sqrt{x + 9} })^{2} = ( {x - 3})^{2} [/tex]
[tex] |x + 9| = {x}^{2} - 6x + 9 [/tex]
_________________________________
[tex]x + 9 = {x}^{2} - 6x + 9[/tex]
Subtract sides 9
[tex]x + 9 - 9 = {x}^{2} - 6x + 9 - 9[/tex]
[tex]x = {x}^{2} - 6x[/tex]
Subtract sides x
[tex]x - x = {x}^{2} - 6x - x[/tex]
[tex] {x}^{2} - 7x = 0[/tex]
[tex]x(x - 7) = 0[/tex]
[tex]x = 0[/tex]
OR
[tex]x - 7 = 0[/tex]
[tex] x = 7[/tex]
_________________________________
[tex]x + 9 = - ( {x}^{2} - 6x + 9)[/tex]
[tex]x + 9 = - {x}^{2} + 6x - 9[/tex]
Subtract sides 9
[tex]x + 9 - 9 = - {x}^{2} + 6x - 9 - 9 \\ [/tex]
[tex]x = - {x}^{2} + 6x - 18 [/tex]
Subtract sides x
[tex]x - x = - {x}^{2} + 6x - 18 - x [/tex]
[tex] - {x}^{2} + 5x - 18 = 0[/tex]
Multiply sides by -1
[tex] {x}^{2} - 5x + 18 = 0 [/tex]
[tex]x = No \: \: solution[/tex]
♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️
CHECK the roots :
[tex]x = 0[/tex]
[tex] \sqrt{0 + 9} ≠0 - 3[/tex]
[tex] \sqrt{9} ≠ - 3[/tex]
[tex]3≠ - 3[/tex]
Thus (( x = 0 )) is unacceptable.
+++++++++++++++++++++++++++++++++++++++
[tex]x = 7[/tex]
[tex] \sqrt{7 + 9} = 7 - 3[/tex]
[tex] \sqrt{16} = 4[/tex]
[tex]4 = 4[/tex]
Thus (( x = 7 )) is the only solution for x.

Let us check whether or not we have found out the correct value of x , by placing -16 in the place of x :-
[tex] - 16 + 21 = 5[/tex]
[tex] 5=5[/tex]
[tex]\color{hotpink}LHS = RHS [/tex]
As the left hand side of the equation is equivalent to the right hand side of the equation, we can conclude that we have found out the correct value of x .
