No. Because for example
4+5 is 9, which has 2 terms (4,5)
BUT
3+5+1 also equals 9, which has 3 terms (3,5,1)
Both equations are equivalent to eachother, but do not have the same amount of terms. This also goes for multiplication.
10x10 is 100, which has 2 terms
BUT
5x10x2 is also 100, which has 3 terms, therefor the answer does not determine the amount of terms in an equation.
Answer:
y = 16.3
Step-by-step explanation:
We would apply the formula for altitude of a right triangle which is given as:
h = √(xy)
Where,
h = 14
x = 12
y = y = ?
Plug in the values
14 = √(12*y)
14² = (√(12*y) (squaring both sides)
196 = 12*y
196/12 = 12y/12 (division property of equality)
16.3 = y (nearest tenth)
y = 16.3
Answer:
see explanation
Step-by-step explanation:
the sum to n terms of an arithmetic sequence is
= [2a + (n - 1)d ]
where d is the common difference and a is the first term
here d = 9 - 7 = 7 - 5 = 2 and a = 5, hence
= [(2 × 5) + 2(n - 1) ]
= (10 + 2n - 2)
= (2n + 8)
= n² + 4n
When sum = 165, then
n² + 4n = 165 ← rearrange into standard form
n² + 4n - 165 = 0 ← in standard form
(n + 15)(n - 11) = 0 ← in factored form
equate each factor to zero and solve for n
n + 15 = 0 ⇒ n = - 15
n - 11 = 0 ⇒ n = 11
but n > 0 ⇒ n = 11
Answer:
9
Step-by-step explanation:
Divide 135 by 15.
