Option: step 2.
Because the student divided only the right side by 2. If you divide one side by a number you have to do the same with the other side to maintain the equality.
Find lcm of 28 and 36 which is 252. They will meet again in another 252 days.
Hi there!
The answer is B.
Since the middle length of the kite is 3 + 3 (which is 6), we find the area of both triangles and add them up.
6 × 10 ÷ 2 = 60 ÷ 2 = 30
6 × 20 ÷ 2 = 120 ÷ 2 = 60
30 + 60 = 90
The answer is B.
Hope this helps!

Step-by-step explanation:
The given quadratic equation is expressed as
x² = 5 - x
Rearranging the equation to take the standard form of ax² + bx + c, it becomes
x² + x - 5 = 0
The general formula for solving quadratic equations is expressed as
x = [- b ± √(b² - 4ac)]/2a
From the equation given,
a = 1
b = 1
c = - 5
Therefore,
x = [- 1 ± √(1² - 4 × 1 × - 5)]/2 × 1
x = [- 1 ± √(1 - - 20)]/2
x = [- 1 ± √21]/2
x = (- 1 + √21)/2 or x = (- 1 - √21)/2
Answer:
h = (m/4 - as)/s
Step-by-step explanation:
s = m / 4(a+h)
(a+h) · s = m/4 ><em>multiplied </em><em>(a+h)</em><em> on both side</em>
as + hs = m/4 ><em>distributed the </em><em>s</em><em> to </em><em>(a+h)</em>
hs = m/4 - as ><em>subtracted </em><em>as</em><em> on both side</em>
h = (m/4 - as)/s<em> >divided </em><em>s</em><em> on both side</em>
