HELP FAST!!!What are the solutions to the quadratic equation (x+3)^2=49

PLEASE HELPPP ASAPP!! Combine and simplify the following radical expression.

Greeley [361]

After demonstrating the procedure by algebraic means, the expression $(2\sqrt[3]{12} )\cdot (3\sqrt[3]{2} )$ is equivalent to $6\cdot \sqrt[3]{24}$ .

In this question we proceed to simplify $(2\sqrt[3]{12} )\cdot (3\sqrt[3]{2} )$ by algebraic means into a single radical expression when possible, whose procedure is shown below and explained by appropriate definitions and theorems:

$(2\sqrt[3]{12} )\cdot (3\sqrt[3]{2} )$ Given.
$(2\cdot 3) \cdot (\sqrt[3]{12} \cdot \sqrt[3]{2} )$ Commutative property/ Associative property.
$6\cdot \sqrt[3]{24}$ Definition of cubic root/ $\sqrt[n]{a} = \sqrt[n]{b}$ /Result

After demonstrating the procedure by algebraic means, the expression $(2\sqrt[3]{12} )\cdot (3\sqrt[3]{2} )$ is equivalent to $6\cdot \sqrt[3]{24}$ .

What is the equivalent fractuon of 2 1/2

irina [24]

Answer:

5/2

Step-by-step explanation:

In order to make the fractions equivalent, you need to place the whole number INTO the fraction itself. By doing so, your answer will be 5/2

Hope this helps :)

At one show he places three mirrors: A, B and C, in a right triangular form. If the distance between A and B is 15 more than the

Butoxors [25]

Answer:

60

Step-by-step explanation:

We have the following sides:

AB, AC, BC

By means of the statement we know that:

The distance between A and B is 15 more than the distance between A and C, that is:

AB = AC + 15

The distance between B and C is 15 less than the distance between A and C

BC = AC - 15

We can infer that the longest side is AB, therefore being right triangular form, we have to:

AC ^ 2 + BC ^ 2 = AB ^ 2

Replacing we have:

AC ^ 2 = AB ^ 2 - BC ^ 2

AC ^ 2 = (AC + 15) ^ 2 - (AC - 15) ^ 2

AC ^ 2 = (AC ^ 2 + 30 * AC + 225) - (AC ^ 2- 30 * AC + 225)

AC ^ 2 = 60 * AC

AC = 60

Which means that the distance between mirror A and C is 60.

To check, we have:

AB = (60 ^ 2 + 45 ^ 2) ^ (1/2) = (5625) ^ (1/2) = 75

AB = AC + 15 = 60 + 15 = 75
