Anybody know how to do this? i need !

Hi there! The first answer is correct.

You start with $5 and save $10 a week until you have at least $45. This situation is represented by the equation, because the variable 10w makes sense with this story and because we have a greater than or equal sign. This means that the left side of the inequality (the savings) must be greater than or equal to $45.

The length of the third side of the triangle is 8 units

Step-by-step explanation:

Here, since the two sides are adjacent a square, what this means is that the length of the square equals the length of the sides of the triangle adjacent to it.

Mathematically, the formula for the area of a square is L^2

With an area of 32 square units, the length of the side of this triangle is thus √(32) =

4√2 units

So we have two sides of the right triangle with length 4√2 units

Now we should know that this right triangle is an isosceles right triangle since the lengths of the adjacent and the opposite are equal.

Now to calculate the length of the third side which is the hypotenuse, we make use of the pythagoras’ theorem which states that the square of the longest side of a right triangle which is the hypotenuse is equal to the sum of the squares of the other two sides

Thus mathematically, the square of the hypotenuse length is 32 + 32 = 64

Let’s call the hypotenuse h for documentation purposes

h^2 = 64

h = √64

h = 8 units
