Answer:
3
Step-by-step explanation:
let's say ishaan is x years old that makes Ben 4x years old
since 4x is 6 more than x we can create an equation like this
4x = x + 6
3x = 6 and x = 3
(x+5)(x-5)
= x^2 - 5x + 5x - 25
= x^2 - 25
(5x+3)(5x-3)
= 25x^2 - 15x + 15x - 9
= 25x^2 - 9
do you see the pattern? both the coefficient on x and constant multiply together to make a perfect square and the middle term, also known as "b" term cancels out leaving a binomial
When a sequence of numbers increases or decreases by a set amount (addition and subtraction)
Answer:
105
Step-by-step explanation:
Remember PEMDAS
1/2 x 4 = 2
2 x 48 = 96
You should now have 9 + 96
9 + 96 = 105
Answer:
p =9
q =2
Step-by-step explanation:
4p + 4q = 44 -----------(I)
4p - 4q = 28 -------------(II)
Add the equations and thus q will be eliminated and we can find the value of p.
(I) 4p + 4q = 44
(II) <u>4p -4q = 28</u> {Now add}
8p = 72
p = 72/8
p= 9
Plugin p = 9 in equation (I)
4*9 + 4q =44
36 + 4q = 44
4q = 44 - 36
4q = 8
q = 8/4
q = 2
