Answer:
I think the answer is B, because the value does increase by one
A. is D=C+26
B is no
C. is <span>because in each age difference, it is a 26 year age difference. SO you would add 26 to 18, which would give you 44 year old. </span>
The LCD of 11/20 and 31/45 is 180
20 40 60 80 100 120 140 160 180
45 90 135 180
Answer:
40 meters
Step-by-step explanation:
Same premise as the other question. 12 ÷ 2 = 6 (for the double dashes) and 8 ÷ 2 = 4 (for the single dashes). Add all the numbers up:

Answer:
1. x = ±9
2.
3. 12 and -12.
4. Antoine is incorrect. There exists two solutions x=5 and x= -5.
Step-by-step explanation:
According to the questions,
Problem 1.
i.e.
i.e. x = ±9.
Problem 2.
i.e.
i.e.
i.e.
Problem 3. [tex]f(x)=x^{2}-144[tex]
To find the roots, we take, [tex]x^{2}-144=0[tex] i.e. [tex]x^{2}=144[tex] i.e. x = ±12.
Thus, the options are 12 and -12.
Problem 4. We have [tex]f(x)=x^{2}+25[tex]
For the roots, we take, [tex]x^{2}+25=0[tex] i.e. [tex]x^{2}=25[tex] i.e. x = ±5.
Thus, Antoine is not correct and two solutions namely x=5 and x= -5 exists.
