Solve: sqrt(x+9) = x-3
♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️
[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.

Here are two similar rectangles.
4 cm
4.8 cm
7 cm
Work out the area of the larger rectangle.
Answer:
[tex]40.32cm^{2}[/tex]
Step-by-step explanation
4*1.2=4.8
7*1.2=8.4
8.4*4.8=40.32
A rectangle is a two-dimensional shape where the length and width are different.
The length and width of the larger rectangle are 4.8 cm and 8.4 cm.
The area of the larger rectangle is 40.32 cm².
What is a rectangle?A rectangle is a two-dimensional shape where the length and width are different.
The area of a rectangle is given as:
Area = Length x width
We have,
Two similar rectangles:
Smaller rectangles:
Length = 4 cm
Width = 7 cm
Larger rectangles:
Length = 4.8 cm
We need to find the width of the larger rectangle.
Since the two rectangles are similar.
4 cm = 4.8 cm
Multiply 7/4 on both sides.
7/4 x 4cm = 7/4 x 4.8 cm
7 cm = 8.4 cm
Now,
Larger rectangle:
Length = 4.8 cm
Width = 8.4 cm
Now,
The area of the larger rectangle:
Area = Length x width
Area = 4.8 x 8.4
Area = 40.32 cm²
Thus,
The area of the larger rectangle is 40.32 cm².

The LCM of 50, 120, and 225 is 5.
True or False
False, the LCM of 50, 120 and 225 is 1800.
5 is the GCF of 50 120 and 225, not the LCM.
Hope it helps!
Answer:
The answer is False
Step-by-step explanation:
5 is the smallest number that can fit into all 3 numbers.
Name the remainder for the quotient and describe or show how you found the remainder.
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)

There are 10 marbles in a bag 1/5 are red and the others are blue. What is the ratio of red to blue marbles?
Answer:
1:4 ratio
Step-by-step explanation:
The Answer is a 1:4 ratio because 1/5 of 10 is 2 and 4/5 of 10 is 8 so the ratio would look like 2:8. You would then simplify 2:8 to 1:4.
Ratio of red to blue marbles is 1:5
An equation is used to show the relationship between two or more numbers and variables.
10 marbles in a bag 1/5 are red and the others are blue.
number of red marbles = 1/5 * 10 = 2
number of blue marbles = 10 - 2 = 8
