First we need to factor the left side. Since it is a perfect square (as is the process with completing the square, we know we can take half of the middle number along with x to be in the two parenthesis.
(x - 4)(x - 4) = 25
Now we simplify to show it as a square.
(x - 4)^2 = 25
Next we take the square root of both sides
x - 4 = +/- 5
Note that we have plus or minus 5. This is because either square would give us positive 25. Now we add 4 to both sides
x = 4 +/- 5
4 + 5 = 9
4 - 5 = -1
Answer:
1. <u>2448</u> do 612x4
2.she got <u>$23 </u>because he has four children and splits all do 72 divide by 4 and add 5 and thats ur answer
hope this helped
To find AB(x) and BC(y), you can do(there are multiple ways you can do this):
tan A = 
tan 60° = or (tan 60°) · 7 = y
tan 60° = 
√3 · 7 = y
7√3 cm = y
sin B = 
sin 30° = or 
sin 30° = 
= 
x = 
x = 14 cm
AB = 14cm
BC = 7√3 cm
Please provide a correct formula of your polynomial.
Where are the signs of (4x^2) and (3x)???
