Answer:
x = 900/ 10 + 3fo
Step-by-step explanation:
Move all terms to the left side and set equal to zero. Then set each factor equal to zero.
Answer:
Let m∠BCE = x
Then m∠ACE = x as well since CE is bisecting ∠ACB.
- m∠ACD + x + x = 180° ⇒
- m∠ACD = 180° - 2x
Consider ΔBEC
<u>Since BE = EC, the opposite angles are congruent:</u>
<u>Then:</u>
<u>Find the angle BEC:</u>
- m∠BEC = 180° - (x + x) = 180° - 2x
<u>Comparing the above we see that:</u>
A square has 4 sides.
If the perimeter around the square is 12cm, then you do 12 ÷ 4, which is 3.
Each side is 3cm long.
Answer:
Step-by-step explanation:
<u>We know that:</u>
- Slope Formula = y₂ - y₁/x₂ - x₁
<u>Solution:</u>
- y₂ - y₁/x₂ - x₁ = -4 - 4/4 - 4
- => -8/0 = undefined
Since the slope of the line is un-defined, the line is vertical. Please look at my graph to understand better.

Hope this helps!!! :)
Step-by-step explanation:
#1: if there is buy 1 get 1 free, then buy 6 get 3 free. so 2.8 times 3 = $8.4
#2: 4 for $3. break it up to 1 for $0.75. now 0.75 times 6 = $4.5
#3: the second one. $4.5 < $8.4
#4: 45 times 12 = $54
