Answer:

Step-by-step explanation:
+6x-5=0
we divide the coefficient of the X by half :
in this case: 6/2 = 3 , then we do the following
The result obtained is raised to square power: 3^2=9
we sum and subtract by 9 to maintain the balance of the equation:
+6x+9-9-5=0
we have:
-9-5=0
= 14
lets apply square root on both sides of the equation:

we know:

so we have:
abs(x+3)=
from where two solutions are obtained

finally we have:

The intersection is at (2,-1)
Answer:
3.5 Oz of chocolate
Step-by-step explanation:
1.6 lb of cookie dough is made from chocolate of 8 Oz
1 lb will be made by 8/ 1.6 = 0.5 Oz of chocolate
Therefore
7lb of cookie dough will be made from 7 * 0.5= 3.5 Oz of chocolate/
Answer:
x = 4.712145
Step-by-step explanation:
Given a=20 and b=28,
c = 4√74 = 34.409301068171
∠α = 35.538° = 35°32'16" = 0.62025 rad
∠β = 54.462° = 54°27'44" = 0.95055 rad
Area = 280
Perimeter = 82.409301068171

Let's solve your equation step-by-step.
9x−8=34.409301
Step 1: Add 8 to both sides.
9x−8+8=34.409301+8
9x=42.409301
Step 2: Divide both sides by 9.

x=4.712145

Answer: 2, 3, 6, 8 (top) 1.40, 2.10 4.20, 5.60 (bottom)
Step-by-step explanation: If 1 pound = 0.70, then 2*0.70=1.40. 2.10 divided by 0.70=3. 0.70*6=4.20. 0.70*8=5.60.
