Step-by-step explanation:
Given formula
an = n² + 4
Now the first four terms of the sequence are
a1 = 1² + 4 = 5
a2 = 2² + 4 = 4 + 4 = 8
a3 = 3² + 4 = 9 + 4 = 13
a4 = 4² + 4 = 16 + 4 = 20
The terms are
5 , 8 , 13 and 20.
Answer:
please check the explanation.
Step-by-step explanation:
Let suppose we have a number = n
The negative reciprocal of 'n' = -1/n
Taking the product of 'n' and its negative reciprocal '-1/n':

remove parentheses: (-a) = -a





Canceling the common factor (the number itself) will bring -1.
It proves that the multiplication of any number and its negative reciprocal will always yield -1.
The question is an example of a ratio problem. This implies that

Therefore, le the number of domestic vehicles be x. We can say that;

Answer: 1458
Nice
4s=amount of grams of protine in straberry for s ounces
3b=amount of grams of protine in banana for b ouces
total ounces is 6
s+b=6
total grams is 22
4s+3b=22
s+b=6
4s+3b=22
those are the 2 equations
a.
s+b=6
4s+3b=22
b. elmination, we can elminate alll the b's and have 1s left
c.
multiply first equaiton by -3 and add to second
4s+3b=22
<u>-3s-3b=-18 +</u>
1s+0b=4
s=4
sub
s+b=6
4+b=6
minus 4
b=2
4 oz straberry
2 oz banana
