Answer:

id

Step-by-step explanation:

The square root equations could have extraneous solutions.

An extraneous solution is a “false” solution to an equation. An extraneous solution does not satisfy the original equation, even though we took seemingly valid steps while solving the equation.

When we solve an equation with containing a radical expression, we have to isolate the radical on one side from all other terms and then square both sides of the equation.

When we square a radical equation we sometimes get a solution to the squared equation that is not a solution to the original equation. Such an equation is called an extraneous solution.

Hence, the square root equations could have extraneous solutions.

Answer:

1 1/4

Step-by-step explanation:

The tallest flower is 2 1/2 the shortest is 1 1/4

Subtract those

2 1/2 = 2 2/4

2 2/4 - 1 1/4 = 1 1/4

your answer is 1 1/4

The answer is 2, 3*4= 12 and 4*2=8. if you add both of them you get 20.

Answer:

√ 7

.........................

7 1/2 in radical form is √15 / √2 x  √15 / √2.

To convert the mixed number 7 1/2 to radical form, we need to rewrite it as an improper fraction and then simplify.

First, let's convert the mixed number to an improper fraction:

7 1/2 = (2 x 7 + 1)/2 = 15/2

Next, we can represent 15/2 in radical form by taking the square root of the numerator and the denominator separately:

√(15/2)² = √15 / √2 x  √15 / √2

The square root of 15 cannot be simplified further, so we leave it as √15.

Therefore, 7 1/2 in radical form is √15 / √2 x  √15 / √2.

Answer:

3 1/5

Step-by-step explanation:

Okay, this is a standard division problem, so our equation is:

2 2/5 ÷ 3/4

but then we have to covert the mixed number to an improper fraction:

12/5 ÷ 3/4

do the cross thingy:

4/5 x 4/1 = 16/5 = 3 1/5

So Jason can cut 3 1/5 sections or 3 if you round

Answer:

10.8kg

Step-by-step explanation:

Before he was on the diet he already weighed 80 kilograms, so it is not important to determining how much weight we gains in two months.  Instead we need to focus on the 5.4t part of the equation.  t represents the number of months so we need to substitute 2 for t and you get

5.4t

Answer: B. 26

Step-by-step explanation:

The options are:

A. 21

B. 26

C. 9

D. 15

Let the third side of the triangle be x.

Since the two sides of a triangle measure 17 inches and 9 inches, therefore we can form a triangle inequality with the figures given. This would be:

x + 9 > 17

x > 17 - 9

x > 8

Also,

x < 9 + 17

x < 26

Therefore, 8 < x < 26

Therefore, the answer is 26.

Answer:

see below

Step-by-step explanation:

Answer:

x = √53

Use the pythagorean theorem to solve for x, which would be c in the equation a^2 + b^2 = c^2.

(a and b are the sides that meet up in a right triangle, c is the hypotenuse. In this case, you are solving for the hypotenuse.)

Step-by-step explanation:

1. Plug in the numbers in the pythagorean theorem.

2^2 + 7^2 = c^2 (remember, each variable is squared)

2. Simplify.

4 + 49 = 53

Since each variable in the pythagorean theorem is squared, the side value would be √53.

Answer:

Simplified form of [tex]\frac{x+1}{x^2+x-6}\div \frac{x^2+5x+4}{x-2}[/tex] is [tex]\mathbf{\frac{1}{(x+3)(x+4)} }[/tex]

Option A is correct answer.

Step-by-step explanation:

We need to find simplified form of [tex]\frac{x+1}{x^2+x-6}\div \frac{x^2+5x+4}{x-2}[/tex]

Solving the given expression:

[tex]\frac{x+1}{x^2+x-6}\div \frac{x^2+5x+4}{x-2}[/tex]

First we find factors of [tex]x^2+x-6[/tex]

[tex]x^2+x-6 \\= x^2+3x-2x-6\\= x(x+3)-2(x+3)\\=(x-2)(x+3)[/tex]

So, factors of [tex]x^2+x-6[/tex] are [tex](x-2)(x+3)[/tex]

Now, fining the factors of [tex]x^2+5x+4[/tex]

[tex]x^2+5x+4\\=x^2+4x+x+4\\=x(x+4)+1(x+4)\\=(x+1)(x+4)[/tex]

So, factors of [tex]x^2+5x+4[/tex] are [tex](x+1)(x+4)\\[/tex]

Now the given expression will become:

[tex]\frac{x+1}{(x-2)(x+3)}\div \frac{(x+1)(x+4)}{x-2}[/tex]

Now, converting division sign into multiplication sign:

[tex]=\frac{x+1}{(x-2)(x+3)}\times \frac{x-2} {(x+1)(x+4)}\\Cancelling, \:common\:terms\\=\frac{1}{(x+3)(x+4)}[/tex]

So, simplified form of [tex]\frac{x+1}{x^2+x-6}\div \frac{x^2+5x+4}{x-2}[/tex] is [tex]\mathbf{\frac{1}{(x+3)(x+4)} }[/tex]

Option A is correct answer.
