A builder needs to tile a 7 foot by 8 foot room with one-foot square tiles. how many tiles will she need?

Diano4ka-milaya [45]

I believe that she will need 56 square tiles. You get this by doing 7 times 8 which is 56. Then, since each tile is a one-foot square tile, you would need 56 tiles to cover the whole floor.

Find K such that the points (-2, 5), (2, 8) and (6, K) are collinear.

damaskus [11]

Answer:

k = 11

Step-by-step explanation:

let the points be A(-2,5), B(2,8), C(6,K).

for the points to be collinear slope of line AB maust be equal to line BC.

slope of line AB = $\frac{8-5}{2+2}=\frac{3}{4}$

slope of line BC = $\frac{k-8}{6-2}=\frac{k-8}{4}$

therefore $\frac{k-8}{4}= \frac{3}{4}$

therefore k = 8 + 3

k = 11

Differentiate y= ln (6 – 3x)^4

dsp73

Step-by-step explanation:

$\frac{dy}{dx} = \frac{1}{ {(6 - 3x)}^{4} } \times {4(6 - 3x)}^{3} ( - 3) \\ = \frac{ - 12 {(6 - 3x)}^{3} }{ {(6 - 3x)}^{4} } \\ = - \frac{12}{6 - 3x}$

I hope I'm correct. I've never learnt differentiation for log and exponents before

Which trinomials are perfect square trinomials?

LiRa [457]

Hello my dear Fancy Nancy!

m² + 10m + 100 ( We cannot factorize this)
m² +36m + 60 ( we cannot factorize this as well)
m² + 24m + 144 ( yes we can factorize this and we will get (x + 12)(x+12)
m² + 10m + 25 ( yes we can and we get (x+5)(x+5)

The correct option is : C and D
