Answer:

$91 is the answer.

Step-by-step explanation:

R = 6%

P = $70

T = 5 year

now

I = PTR/100

=(70×5×6)100

= 2100/100

= $21

So,

I = A-P

21 = A-70

21+70 = A

so, A = $91

Readme [11.4K]

Let
x--------> represents the length of a single tile
L-------> the length of the floor
W------> the width of the floor
A--------> area of a tiled kitchen floor

we know that
A=W*L
A=4x² + 24x + 27
so
W*L=4x² + 24x + 27---------> equation 1
L=2x+9------> equation 2

substitute equation 2 in equation 1
W*[2x+9]=4x² + 24x + 27
W=[4x² + 24x + 27]/[2x+9]

therefore

the answer is
the expression that represents the width of the kitchen in terms of x is
W=[4x² + 24x + 27]/[2x+9]

Answer:

x-6

Step-by-step explanation:

The mistake when expanding the bracket 3(x-6),3 was supposed to multiply 6 but instead it was added to 6 instead

the correct working

3(x-6)+(4x+12)-6x

3x-18+4x+12-6x

(3x+4x-6x)+(-18+12)
