Step-by-step explanation:
2(x+3)
2x+6
devide each in 2
2x/2 and 6/2
2 and 2 go out
X=3
Let
x---------------> number of <span>bulbs produced per year
n--------------> number of years
</span>we know that
the pattern can be modeled through the following equation
x=6*[2^(n-1)]
for n=1 year
x=6*[2^(1-1)]----------> 6 bulbs
for n=2 year
x=6*[2^(2-1)]----------> 12 bulbs
for n=3 year
x=6*[2^(3-1)]----------> 24 bulbs
for n=8 year
x=6*[2^(8-1)]----------> 6*128=768 bulbs
the answer is 768 bulbs
Answer:
x = 1/4 k
Step-by-step explanation:
11kx + 13kx = 6
(11k+13k)x = 6
24kx = 6
x = k/4
Answer:
x^2+x+1
Step-by-step explanation:
(x-2)+(x^2+3)=x-2+x^2+3=x^2+x-2+3=x^2+x+1
Root x >7
square x and 7=
