Answer:
x = - 
Step-by-step explanation:
Given
(x - 4) - (x + 7 ) = 8x
Distribute parenthesis noting second is distributed by - 1
x - 4 - x - 7 = 8x ← simplify left side
- 11 = 8x ( divide both sides by 8 )
x = - 
Answer: y = 15
Step-by-Step Explanation:
=> y^2 = 225
Therefore,
y = √225
=> y = 15
Hence, y = 15
Answer:
1.72
Step-by-step explanation:
AB tangent at D, AD = OD = 4
so triangle OAD is right angle with side of 4 and 4.
area of OAD = 1/2 * 4 * 4 = 8
Angle AOD = DAO = 45 deg.
so circular sector OCD area = area of circle O * 45/360
= pi * 4 * 4 * 45/360
= 2pi
Shade area ACD = trigangle OAD - circular sector OCD
= 8 - 2pi
= 1.72
3(5 + 6)
15 + 18 is your answer
Distribute the 3 to both 5 and 6
3 x 5 = 15
6 x 3 = 18
15 + 18 is your expression
hope this helps
