Are you sure you copied the problem down accurately?
No, there are no grounds for stating that 2.2 + 8x + 8 and (x + 4) are equivalent. Explain your reasoning, please.
Answer:
f(0) = 0.25 = 1/4
f(x) = f(x-1) × 2/3
Step-by-step explanation:
a0 = 0.25×(2/3)⁰ = 0.25×1 = 0.25 = 1/4
a1 = 0.25×(2/3)¹ = 0.25×(2/3) = 1/4 × 2/3 = 2/12 = 1/6 =
= a0 × 2/3
a2 = 0.25×(2/3)² = 0.25×(4/9) = 1/4 × 4/9 = 4/36 = 1/9 =
= a1 × 2/3
=>
an = an-1 × 2/3, n >= 1
but what about negative x ?
is a0 = a-1 × 2/3 ?
so, yes, a0 = a-1 × (2/3)
and a-1 = a-2 × (2/3)

Answer:
(z−5)(z−5)
Step-by-step explanation:
Let's factor z2−10z+25
z2−10z+25
The middle number is -10 and the last number is 25.
Factoring means we want something like
(z+_)(z+_)
Which numbers go in the blanks?
We need two numbers that...
Add together to get -10
Multiply together to get 25
Can you think of the two numbers?
Try -5 and -5:
-5+-5 = -10
-5*-5 = 25
Fill in the blanks in
(z+_)(z+_)
with -5 and -5 to get...
(z-5)(z-5)
Answer:
$25.50
Step-by-step explanation:
We need to find 30% of 85:
30%*85
Convert 30% to a fraction to make the math easier:
She tipped the waiter $25.50
Answer:
7 inches
Step-by-step explanation:
The ratio of width to length of the known rectangle is 4 : 14 and this simplifies to 2 : 7.
The smaller similar rectangle will have the same ratio of 2 :7.
This can also be looked at another way. The second value in the ratio is 7/2 of the first value in the ratio and the first value is 2/7 of the second value.
Example:
7/2 * 2 = 7
Example:
2/7 * 7 = 2
