An expression is a sentence with at least two numbers or variables having mathematical operation. Math operations can be addition, subtraction, multiplication, division.

For example, 2x+3

Given that,

An expression,7x + 2

here, 7 is coefficient

x is variable

And then in 7x, constant number 2 is added

So it can be state that a number multiplied by seven then added to two

So, the statement is 7 multiplied in number then 2 is added

A right triangle has legs with lengths of 6in and 8in. What is the length of the hypotenuse

Answers

You require the Pythagorean Theorem: in a right triangle the sum of the squares of the legs equals the square of the hypotenuse.
In this case 6^2 + 8^2 = 36 + 64 = 100 = 10^2, i.e. the hypotenuse is 10.
Please note that a so-called 3-4-5 right triangle is the smallest right triangle which has integer sides...and of course, a 6-8-10 triangle like this one is simply a magnification of the smaller, i.e. a so-called similar triangle.

Answer: 10

Step-by-step explanation:

the formula is √a^2+b^2=c^2

so your equation should look like this √6^2+8^2=c^2

6·6=36

8·8=64

√36+64

√100=10

the hypotenuse or c^2 is 10

Jenny selects a box of cereal for her family at the supermarket. Across town, Chase also happens to pick out a box of cereal for his own family. Are these two events dependent or independent?

Answers

Answer:

Independent

Step-by-step explanation:

In clear and simple terms, Events A and B are sid to be independent if the occurrence of event A and event B can occur simultaneously, that is the occurrence of A does not affect or stop the occurrence of B at the time.

The events being compared can happen concurrently with Jenny and chase both making selection for their respective families. However, events which cannot occur together are called mutually exclusive events such as obtaining a head and tail from a single coin toss, this events cannot happen together and are thus not independent.
