Answer: 138x + 27
Step-by-step explanation:
First you distribute the 3, creating 102x +27.
Then you combine like terms, creating 138x + 27
You can't do anything else so that's your answer.
Answer:
EB=20, BC=8, AC=16
Step-by-step explanation:
The symbols indicate that:
AB=BC and AE=ED
EB and CD are parallels
AB=BC=8
AC= AB+BC
AC= 8+8
AC=16
To find EB we can use the Cosine Law
For the upper triangle x=∡EAB:
EB^2 = AB^2 + AE^2 -2*AB*AE*Cosx
AB*AE*Cosx= -(EB^2-AB^2 - AE^2)/2 (Part I)
For de big triangle:
DC^2= AC^2+AD^2 -2AC*AD*Cosx
Also:
AC=2*AB
AD=2*AE
DC^2= (2*AB)^2 + (2*AE)^2 -2(2*AB)(2*AE)*Cosx
DC^2= 4*AB^2 +4*AE^2- 8*AB*AE*Cosx
AB*AE*Cosx =-(DC^2-4*AB^2 -4*AE^2)/8 (Part II)
Part I= Part II
-(EB^2-AB^2 - AE^2)/2= -(DC^2-4*AB^2 -4*AE^2)/8
Extracting EB:
EB^2=DC^2/4
EB=DC/2
EB=40/2
EB=20

Step-by-step explanation:
Q1
- 6 + ∛3x² = 18
- ∛3x² = 12
- 3x² = 12³
- 3x² = 1728
- x² = 1728/3
- x² = 576
- x = √576
- x = ±24
Option D
Q2
- ∛3x² - 5 = 10
- ∛3x² = 15
- 3x² = 15³
- 3x² = 3375
- x² = 1125
- x = √1125
- x = ± 15√5
Option A
Q3
- 3∛x² - 2 = 7
- 3∛x² = 9
- ∛x² = 3
- x² = 3³
- x² = 27
- x = √27
- x = ±3√3
Option C
Q4
- ∛4x² + 2 = 9
- ∛4x² = 7
- 4x² = 7³
- 4x² = 243
- x² = 243/4
- x = √243/4
- x = ± 7√7/2
Option D
