Answer:
-1
Step-by-step explanation:
-3-2=-5
4-(-1)=5
-5/5 simplifies to -1
Answer:
1. B>-7 2. M is > or = to 8.8 3. Y < 1/2
Step-by-step explanation:
Step-by-step Answer:
Step 1:
Extract factor(s) common to all terms.
In this case, the HCF is 3, so the expression is written
-12x^2+45x+12 = -3(4x^2-15x-4)
The negative sign was also exrracted to give a positive leading coefficient, which is easier to work with.
Step 2, group the coefficient in such a way that there is a common factor.
Leaving the factor -4 for the moment, and concentrate on the coefficients in parentheses, write the original expression as
4x^2 - 15x -4
= 4x^2 -16x
+ x -4
= 4x*(x-4) + 1*(x-4)
extract (x-4) as a common factor
= (x-4)(4x+1)
Step 3:
Combine all the factors to get
-3(x-4)(4x+1)
=3(4-x)(4x+1)
as the complete factoring of the given expression.
Answer:
what is x
Step-by-step explanation:
way to solve for this is to set up the base and height. then you can use the area (if given) to divide the area from the side you know to get your answer.
If we flip three coins, we get:
H H H
H H T
H T H
T H H
H T T
T H T
T T H
T T T
Based on our sample space, we have three ways to get two tails.
