Answer:
- 3, - 2, - 1 and 6
Step-by-step explanation:
To find the first 3 terms, substitute n = 1, 2, 3 into the nth term rule
a₁ = 1 - 4 = - 3
a₂ = 2 - 4 = - 2
a₃ = 3 - 4 = - 1
The first 3 terms are - 3, - 2, - 1
similarly substitute n = 10 into the rule for 10th term
a₁₀ = 10 - 4 = 6
Answer:
1) B. n ≥ 3
2)A. 5x – 9
Step-by-step explanation:
1)
If the least value of n is 3 then all the values of n must be greater or equal to 3
Thus the correct option is B :n ≥ 3
2)
Given:
Milo's age is 9 years less than 5 times Pearl's age
Pearl's age is x years
5 times Pearl's age= 5x
then milo's age= 5x-9
so the correct option is A. 5x – 9 !
Answer:
=4x^2−20xy+25y^2
Step-by-step explanation:
(2x−5y)^2
=(2x+−5y)(2x+−5y)
=(2x)(2x)+(2x)(−5y)+(−5y)(2x)+(−5y)(−5y)
=4x^2−10xy−10xy+25y^2
=4x^2−20xy+25y^2
Hope it helped!
Step-by-step explanation:
2x-9y+7x+20
9x - 9y +20
Answer:
1/36
Step-by-step explanation:
(-6) ^-2
The negative in the exponent means in goes from the numerator to the denominator
(-6) ^-2 = 1/ (-6)^2
We know that
(-6)^2 = -6*-6 = 36
(-6) ^-2 = 1/ 36
