Answer:
4≤w≤6
Step-by-step explanation:
24 ≤ w (w + 2) ≤ 48 = 4≤w≤6
Answer:
Step-by-step explanation:
4x - (x + 3) +5(2x - 8) = 4x + x*(-1) + 3*(-1) + 2x * 5 + (-8) * 5
= 4x - x - 3 + 10x - 40 {combine like terms}
= 4x - x + 10x - 3 - 40
= 13x - 43
ANSWER
The correct answer is
EXPLANATION
The expression given to us is,
We plug in
. That means we substitute 12 wherever we see x to obtain,
We simplify the parenthesis first to obtain,
Hence the expression evaluates to
Answer:
Real life example : On a clock, the second hand in the middle of the hour hand and minute hand, is working as the angle bisector.
For a perpendicular bisectors, take two ends of a compass needle, with the long end on the North, the short end is pointing South, and the lines of East and West are on the left and right.
Orthocenter : The orthocenter is the point of intersection of the three altitudes of a triangle. It is the hardest part of the triangle to find because :
- It can lie inside a triangle or outside the triangle as it depends on the type of type of the triangle whether it is acute or obtuse. So, in order to identify it we must first know the type of the triangle.
- And secondly, the formula for finding orthocenter is quite complicated so it is the hardest part of the triangle to identify and use.
Answer: Choice B and D are both correct.
Step-by-step explanation:
The expression has two adjacent negative signs in the middle. The two negative signs are to be multiplied, which then produces one positive sign.
Choice B is therefore correct because the expression becomes 6+6 which is 6 to the right of the number line where the numbers are increasing.
Choice D is also equally correct because the addition of 6 to 6 equals 12(6+6 = 12).
