7x²-14x=0
7x²=-14x
sry idk the rest hope this helped a little bit
Hector : 42-18=24
H = 12(2) because 12 x 2 = 24
24divide16=1.5
W=16(1.5) because 16 x 1.5 = 24
y = 12
Explanation:
We would collect like terms by subtracting 24 from both sides:
Answer:
A
Step-by-step explanation:
The sequence of positive odd numbers is
1, 3, 5, 7, ......
This is an arithmetic sequence with common difference d
d = 3 - 1 = 5 - 3 = 7 - 5 = 2
The sum to n terms of an arithmetic sequence is
= [2a + (n - 1)d ]
where a is the first term
here a = 1, d = 2, n = 12, hence
= [1 + (11 × 2) ]
= 6 [ 2 + (11 × 2) ]
= 6 × 24 = 144 → A
