Answer:
You will do the Distributive Property first.
Step-by-step explanation:
You will do the Distributive Property first.
4(x - 3) = 9 <u>distribute the 4 into the x and -3.</u>
4x - 12 = 9 <u>add -12 to both sides.</u>
4x = 21 <u>divide 4 on both sides.</u>
x = 5.25 is your answer.
If it took you (one person) 3 days to build a doghouse, then it should take 2 people to build it in half the time. So all we have to do is split 3 days in 2.
3/2 = 1.5
So it would take 1 1/2 days or 36 hours for 2 people to complete the doghouse.
Answer:
(x+7)(x-7)
The factors are -7 and 7
Step-by-step explanation:
Given the function x²-49, to find the factors, we will factorise the expressed using the different of two square.
If a and b are two numbers, then based on difference of two square;
a²-b² = (a+b)(a-b)
Applying this to the function in question
x²-49
= x²-7²
= (x+7)(x-7)
The factors can be gotten by equating the function to zero according to factor theorem.
(x+7)(x-7) = 0
x+7 = 0 and x-7 = 0
x = -7 and 7
