B - 4 where B is the variable representing the Bulls score
17) The line that is John is closer to certain but not exactly on certain so I'd say it's "likely"
18) Using that same example as the one above, if 0 means impossible, then 1 means certain. I'd place your label for Sara at 1.
19) Let s = sides of the square. There are 4 sides and all sides are equal so we can set up the equation 4s = 64. Divide both sides by 4. s = 16. Now add 2 to this. 16 + 2 = 18. The length of each side of the original square was 18.
20) If the scale is 1 cm : 1 meter and the height of the model is 16 cm, then the actual plane must be 16 meters.
21) 2x and 100 are supplementary angles meaning together they must add up to 180.
2x + 100 = 180
2x = 180 - 100
2x = 80
Divide both sides by 2
x = 40
22) Assuming 3x is supposed to be the right angle, right angles are 90 degrees.
3x = 90
Divide by 3 on both sides
x = 30.
Answer:
thousandths
Step-by-step explanation:
It is because one of the numbers is lower then the other so in this case 35.1457 is the larger number.
Answer:
(X+2) (X-2) . This is the final answer
Step-by-step explanation:
Solving f(x) = x^2 - 4
A^2 - B^2 is a special case where the original equation before it was foiled is
(A + B) (A - B) because the middle terms will cancel out when foiled.
This means that the equation can be written as
(X + 2)(X - 2) = 0
Each of these you will then set equal to 0 and then solve
X + 2 = 0, X - 2 = 0
X = -2, 2
I hope this helps you! let me now if its right ok <3 :)
