Answer:
37
Step-by-step explanation:
3x + 8x + 4x = 6x + 63 ( combine like terms)
>15x = 6x + 63 (subtract from both sides)
-6x. -6x
-----------------
>9x = 63. (divide both sides by 9)
--------------
9. 9
> x = 7 ( use this to plug in for your new equation)!
5(x) + 2
>5(7) + 2 (multiply 5*7)
> 35 +2 (then add)
> 37 is your answer
What are the two radicals that surround /125
Answer:
[tex]+5\sqrt{5} and -5\sqrt{5}[/tex]
Step-by-step explanation:
The radicals are [tex]+5\sqrt{5} and -5\sqrt{5}[/tex]
as [tex]5\sqrt{5}* 5\sqrt{5} = 125[/tex]
also [tex]-5\sqrt{5} *-5\sqrt{5} = 125[/tex]

On a certain hot summer's day, 151 people used the public swimming pool. The daily prices are $1.50 for children and $2.00 for adults. The receipts for admission totaled $270.50 How many children and how many adults swam at the public pool that day?
Answer: 63 children and 88 adults swam at the public pool that day.
Step-by-step explanation:
Let x = Number of children
y= Number of adults
As per given , we have
x+y=151 (i)
1.50x+2y=270.50 (ii)
Multiply 2 on both sides of (i)
2x+2y = 302 (iii)
Eliminate (ii) from (iii)
0.5x=31.5
⇒ x = 63 [Divide both sides by 0.5]
Put value of x in (i) , we get
63+y= 151
⇒ y= 151-63 =88
Hence, 63 children and 88 adults swam at the public pool that day.

When simplified, StartFraction tangent (40 degrees) minus tangent (10 degrees) Over 1 + (tangent (40 degrees) ) (tangent 10 degrees) ) EndFraction is equivalent to which expression?
Answer:
C. tan(30°)
Step-by-step explanation:
edge yuh yuhhhhh
The equivalent fraction is [tex]\frac{sin 40\textdegree. {cos10\textdegree} - {sin 10\textdegree}{cos40\textdegree}}{{cos 40\textdegree. {cos10\textdegree} + {sin 10\textdegree}{sin40\textdegree}}}[/tex].
The given expression is tan 40°-tan 10°/1+tan 40°.tan 10°.
How do simplify the trigonometric expression?When simplifying trigonometric expressions, one approach is to change everything into sine or cosine.
Now, [tex]\frac{\frac{sin40\textdegree}{cos40\textdegree} -\frac{sin10\textdegree}{cos10\textdegree}}{1+\frac{sin40\textdegree}{cos40\textdegree} .\frac{sin10\textdegree}{cos10\textdegree} }[/tex]
=[tex]\frac{sin 40\textdegree. {cos10\textdegree} - {sin 10\textdegree}{cos40\textdegree}}{{cos 40\textdegree. {cos10\textdegree} + {sin 10\textdegree}{sin40\textdegree}}}[/tex]
Therefore, the equivalent fraction is [tex]\frac{sin 40\textdegree. {cos10\textdegree} - {sin 10\textdegree}{cos40\textdegree}}{{cos 40\textdegree. {cos10\textdegree} + {sin 10\textdegree}{sin40\textdegree}}}[/tex].

the area A (in square feet) of the rectangular shed is given by
6x^3+7x^2+11x+21. use polynomial long division to find an expression for the length (in feet) of the shed
This question is incomplete.
Complete Question
The area A (in square feet) of the rectangular shed is given by 6x³+7x²+11x+21.And one side of the rectangular is 2x+3. Use polynomial long division to find an expression for the length (in feet) of the shed.
Answer:
3x² - x +7
Step-by-step explanation:
Using the long division method:
We have :
Divisor : 6x³+7x²+11x+21
Dividend : 2x+3
Quotient : the length (in feet) of the shed = ???
Hence, we solve below
6x³+7x²+11x+21 ÷ 2x + 3
3x² -x + 7
______________________
2x+3 l 6x³+7x²+11x+21
6x³+9x²
__________
-2x²+11x
-2x²-3x
__________
14x+21
14x+21
