Answer:

√39

Step-by-step explanation:

This triangle is a right triangle, we can use the Pythagoras Theorem.

The hypotenuse or the slanted part of the triangle is c, while the other two are b and a, doesn't matter the order.

In this picture we know what c is and what a (or b, doesn't matter, like I stated before ;w;) is.

a = 5

c = 8

b = x

a^2 + b^2 = c^2

5^2 + x^2 = 8^2

25 + x^2 = 64

x^2 = 64 - 25

x^2 = 39

√x^2 = √39

x = √39

[Right Triangles Only] Pythagorean Theorem: a² + b² = c²

Step-by-step explanation:

Step 1: Identify

Leg a = x

Leg b = 5

Hypotenuse c = 8

Step 2: Solve for x

Substitute [PT]: x² + 5² = 8²
Isolate x term: x² = 8² - 5²
Exponents: x² = 64 - 25
Subtract: x² = 39
Isolate x: x = √39

Answer:

Following are the solution to the given question:

Step-by-step explanation:

In question a:

$\to 16= 4^2$ is a perfect square.

$\to 125 = 5^3$ is not a perfect square

In question b:

$\to 20 = 2 \times 2 \times 5$ , not a perfect square.

$\to 25 = 5^2$ is a perfect square .

$\to 100 = 10^2$ is a perfect square .

$\to 125$ is not a perfect square, its nearest perfect square is $121 = 11^2 .$

$\to 144 = 12^2$ is a perfect square .

$\to 225 = 15^2$ is a perfect square .

$\to 10,000 = 100^2$ is a perfect square .

8(c − 12) = −40 (:3」∠)_ Dem legz

TEA [102]

8(c-12)=40 that gonna be equal to 8c-96=-40 or 8c=-40+96 ,8c =56 divide both sides by 8 that equal to 7.....

sam had 70 erasers and rulers. after giving away 1/3 of his erasers and 10 rulers, he had an equal number of erasers and rulers

Radda [10]

Answer:

36 erasers

Step-by-step explanation:

Let number of erasers be e

let number of rulers be r

We can write:

e + r = 70

and

After giving away, he has

Erasers: 2/3e

Rulers: r - 10

These two are equal, so we can write and solve:

2/3e = r - 10

2/3e + 10 = r

Putting this in initial equation, we have:

e + (2/3e + 10) = 70

5/3e + 10 = 70

5/3 e = 60

e = 36

And rulers is:

r = 2/3(36) + 10 = 34

Hence, he had 36 erasers in the beginning
