Answer:
85
Step-by-step explanation:
Note the mother is 3x his age when he is 25 years old. Multiply 3 with 25:
3 x 25 = 75
Ten years pass (35 - 25 = 10). Add 10 to 75:
75 + 10 = 85
When the man is 35 years old, his mother will be 85 years old.

The correct expression is (a) n = 100; (x + 10)^2
<h3>How to determine the value of n?</h3>
The expression is given as:
x^2 + 20x + n
Take the coefficient of x
k = 20
Divide by 2
k/2= 10
Square both sides
(k/2)^2 = 100
The above value represents the value of n
i.e.
n = 100
So, we have:
x^2 + 20x + 100
Expand
x^2 + 10x + 10x + 100
Factorize
x(x + 10) + 10(x + 10)
Factor out x + 10
(x + 10)^2
Hence, the correct expression is (a) n = 100; (x + 10)^2

Answer:
Step-by-step explanation:
there are more money during the week 1 because having a -$8 balance is better than having a -$10 balance, -8 > -10
week 2 has a greater absolute value
| -10| = 10 and |-8| =8 and becasue 10> 8 then |-10| > |-8|
Answer:
4.1145
Step-by-step explanation:
You can use the following formula to solve this kind of problems,
So, let's start of with log4_(300). Since the question have already gave log4_(3) =0.7925 and log4_(5) =1.1610. It means that you have to split the 300 into the simplest form where almost all of the numbers are 3 and 5.
