The procedure to squaring a two digit number is by multiplying the first number by a integer greater than the number and putting 25 beside it.

Finding the Square of a Value is a simple method. Multiply the specified integer by itself to determine the square number. The square term is always represented as an integer multiplied by two. For example, the square of 5 is 25 multiplied by 5, giving 5×5 = 5² = 25.

What if we want to calculate the square root of a two-digit number . It might be a little challenging. Ordinary multiplication cannot be used to compute the square of two-digit values. This article will show us how to calculate the precise square of such integers.

Simply multiply a single-digit number by itself to find its square. Furthermore, by memorizing the tables from 1 to 10.

We taught about two triangles and how to find the point of any base of a triangle given the other two sides using Pythagoras' theorem.

A right triangle has three sides: the hypotenuse, perpendicular, and base. Pythagoras' theorem states that

Hypotenuse² = Perpendicular² + Base².

13 - 4x = 1 - x<br><br>Step by step please​
Virty [35]

Answer:

13 - 4x = 1 - x

Subtract 13 from both sides.

-4x = -12 - x

Add x to both sides.

-3x = -12

Divide both sides by -3.

x=4

Harry saved $100 each week for 8 weeks. He earned $48 on his savings of $800. What interest did Harry earn for every $100?
ch4aika [34]
<h2>Explanation:</h2><h2></h2>

In this problem, we know that Harry saved $100 each week for 8 weeks. In other words, he saved a total amount of money:

\text{Amount of money saved}=8\times 100=\$800

We know that he earned $48 on his savings of $800, so for every $100 the interest (I) he earns is:

I=\frac{48}{8}=\$6

So, in conclusion Harry did earn $6 in interest for every $100
