Answer:

Solution given:

perpendicular [P]=x

base[B]=9

hypotenuse [H]=41

Now.

By using Pythagoras law

H²=P²+B²

41²=x²+9²

x²=41²-9²

x= $\sqrt{1600}=40$

x=40 is a required answer.

A student's pay of $21 an hour is $6 more than twice the amount the student earns per hour at an internship. Enter and solve an

w = amount she earns for her work.

twice that is 2*w, or 2w.

6 more than that is 2w + 6.

$\bf 21~~\stackrel{is}{=}~~\stackrel{\textit{twice her earnings + 6}}{2w +6}\implies 15=2w\implies \cfrac{15}{2}=w\implies 7\frac{1}{2}=w$

I have a Math Quiz for You Mathmatizers !!! I have a 72" 2x4 with 2 cuts/3 pieces The 2nd piece is twice as long as the 1st piec

olya-2409 [2.1K]

Answer:

the answer is 4

Step-by-step explanation:

let x= length of the first piece.

second piece is 2x, right

third piece x+5, right

Total, in x-talk, is x + 2x + x+5 and that equals 21 feet, right.

Combine like terms: 4x + 5 = 21. Still with me?

So 4x = 16 (do you see why?)

So, what x must x be is 4

Jon has $72 in his bank account. In order to avoid fees, he must maintain a minimum balance of $12. He wants to buy comic books

Vedmedyk [2.9K]

Answer:

40 comic books

Step-by-step explanation:

well i dont see a graph but i can give you x, the number of comic books he can buy!

so if he must have a minimum balance of $12 and right now he has $72 then we subtract those and see how much money he has to spend

so that gives us $60 to spend on the comic books

so if each comic book costs $1.50 then we divide that into the $60 leaving us with

40 comic books that jon can buy!

Solve the equation x. If a solution is extraneous, be sure to identify it in your final answer.

Igoryamba

Answer:

x=2 is the only solution

Step-by-step explanation:

The given expression is;

$\sqrt{x+7}-1=x$

Add 1 to both sides of the equation;

$\sqrt{x+7}=x+1$

Square both sides ;

$(\sqrt{x+7})^2=(x+1)^2$

$x+7=x^2+2x+1$

This implies that;

$x^2+2x-x+1-7=0$

$x^2+x-6=0$

Split the middle term

$x^2+3x-2x-6=0$

$x(x+3)-2(x+3)=0$

$(x+3)(x-2)=0$

x=-3,or x=2

Check for extraneous solutions by substituting into the original equation.

When x=-3,

$\sqrt{-3+7}-1=-3$

$\sqrt{4}-1\ne-2$

This is an extraneous solution.

When x=2,

$\sqrt{2+7}-1=2$

$\sqrt{9}-1=2$

$3-1=2$ . This is true

This is not an extraneous solution
