Answer:
(C
) b(x)=4(x+2)(x−2)
Step-by-step explanation:
We are given
The number of blue tiles in her design is modeled by the function b(x)=
if the no of blue tiles used is zero then
b(x) = = 0
= 4
x = +2 and -2
this is the condition for blue tiles
Modelling
b(x) = 4(x+2)(x-2)
This means when the blue tiles used are zero, then we use 2 red tile on each of the two square of 4 square. so the length will be 4 tiles long and its a square so 4x4 = 16 red tiles.
A+ny = n
a = n-ny
a = (1-y)n
a/(1-y) = n
<span>n = a/(1-y)</span>
Answer:
or simplified
Step-by-step explanation:
Percent means per hundred.
For company a ( $376 + $12 an hr) it would take 2 hours because 376+12= 388+12= 400 (376 + (12 x 2) )
for company b, ( $280 + $15 ) it would take 9 hours because 280 + 15 = 295 + 15 =
310 + 15 = 325 + 15 = 340 + 15 = 355 + 15 = 370 + 15 = 385 + 15 = 400 (280 + (15 x 8))
376 x (12 x 2)
376 x 24 = 400
280 x (15 x 8)
280 x 120 = 400
1) a = 2 hrs
b = 8 hrs
2) $400
