Answer:

x ≈ 6.6

Step-by-step explanation:

Use Pythagoras' identity in the right triangle.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

x² + ( $\sqrt{5}$ )² = 7²

x² + 5 = 49 ( subtract 5 from both sides )

x² = 44 ( take the square root of both sides )

x = $\sqrt{44}$ ≈ 6.6 ( to the nearest tenth )

Help ? , i got like 24 for c but I dont know why,

inessss [21]

I'm not quite sure how you got your answer, but the answer to c is 57 tiles.

First we can find the area of a singular tile by multiplying 12 and 12 together to get 144 in².

Then we find the area of the kitchen floor by splitting it into two rectangles, finding those areas, and adding them. This gives us (108 × 60) + (48 × 36) = 6,480 + 1,728 = 8,208 in².

Then to find how many tiles fit, we need to divide the total area, 8,208 in², by the area of a singular tile, 144 in², which results in 57 tiles.

I hope this helps!

Answer:

W=P-2L / 2

Step-by-step explanation:

P=2(L+W)

P=2L+2W

-2L -2L

P-2L=2W

Hi! So, I know I got this answer wrong, but I wasn't sure how to solve an equation with signs like: [brackets] in it, I've inclu

dimaraw [331]

Step-by-step explanation:

Brackets is the bigger version of parentheses, you first solve the questions inside the parentheses, then move onto brackets.

For example, this question:

$x=-1\\y=-2\\z=3$

$5x-y[7-4(z-y)]$

$5(-1)-(-2)[7-4(3-(-2))]$
$5(-1)-(-2)[7-4(5)]$

$5(-1)-(-2)[7-20]$

$5(-1)-(-2)[-13]$

$-5-(-2)[-13]$

$-5-26$

$-31$

I hope you understand better now.
