Answer:
1.921
Step-by-step explanation:
Answer:
4x^2-81y^2 is NOT a perfect square trinomial, factored. You know this because if you factor this to (2x+9y)(2x-9y) then you will see that the signs between terms in the parenthesis are DIFFERENT.
Step-by-step explanation:
Taking notes as you go through the course will help you retain and process the information much better than getting "help" from a site that is probably badly named.
The answer is 5.
Because take x=1 entry to the graph and going vertical until you intercept the curve, then read the value on the y axial
Answer:
(x+6)(x+2) is the factored equation
(-6, -2) is the coordinates
Step-by-step explanation:
find what multiplies to be 12 and adds to be 8
set each factor equal to 0 and solve for x, which is the coordinates
Answer:
38.5
Step-by-step explanation:
Lets say, first number = x
Second number = 3x+7
Total = 49
(x)+(3x+7)= 49
4x+7 = 49
4x = 42
x = 42/4
x= 10.5
x= 10.5
3x+7 = 3(10.5)+7 = 38.5
Hope this helps!!
