Answer 1

Answer:

Step-by-step explanation:

To find the missing leg, we need to use a^2 + b^2 = c^2.

Let's call the missing leg a, and then substitute the numbers the other numbers

a^2 + 12^2 = 13^2

Simplify

a^2 + 144 = 169

To solve, subtract 144 from both sides (169-144)

a^2 = 25

This means that a squared is 25; to find a, we need to find the square root of 25.

a = 5

Your answer is 5.

Answer 2

Answer:

Step-by-step explanation:

set it up

[tex]12^{2}[/tex]+[tex]a^{2}[/tex]=[tex]13^{2}[/tex]

do what you know

equation becomes: 144+[tex]a^{2}[/tex]=169

subtract both sides by 144

equation becomes [tex]a{2}[/tex]=25

square root both sides

equation becomes: a=5

Aidan buys 3 bicycles for $252. Each bicycle was the same price.

What is the cost of 1 bicycle?

Answers

Answer:84 dollars per bike :)

Step-by-step explanation:

Answer:

$84 each

Step-by-step explanation:

All you are doing for this problem is dividing the total by the amount of bicycles (total = 252) (bicycles = 3) and after dividing you would get $84 per bicycle. To check this work, you can do the inverse operation of division (multiplication) and multiply 3 by 84, to still end up with $252. Hope this helps!

The lengths of the diagonals of a rhombus are 4x and 6x. What expression gives the perimeter of the rhombus?

Answers

Answer:

Expression gives the perimeter = 4x√17

Step-by-step explanation:

∵ The diagonals of the rhombus ⊥ to each other and

bisects each other

∴ Half the longest diagonal = 8x/2 = 4x

∴ Half the shortest diagonal = 2x/2 = x

Use Pythagoras theorem to find the length of the side of the rhombus

∴ The length of the side = √[(4x)² + (x)²] = √[16x² + x²] = √(17x²)

∴ S = x√17

∵ Perimeter of the rhombus = 4 × S

∴ P = 4 × x√17 = 4x√17

the correct answer is 4x✓13.

Answer:

x = - 6, x² = [tex]\frac{7}{2}[/tex]

Step-by-step explanation:

[tex]2x^{2}[/tex] + 12x - 7x - 42 = 0

2x^{2} (x + 6) - 7 (x + 6) = 0

(x + 6) x (2x - 7) = 0

x + 6 = 0

2x - 7 = 0

x = - 6

x = [tex]\frac{7}{2}[/tex]

x = - 6, x² = [tex]\frac{7}{2}[/tex]
