Answer
1/2+2×(sqrt3)^2+x.(sqrt3/2)^2=8+1^2+1/2
1/2+2×3+x.3/4=8+1+1/2
1/2-1/2+6+x.3/4=9
x.3/4=9-6
x.3×4=3
x.3=3×4
x.3=12
x=12/3
x=4.
so, the value of x is 4.
hope it helps you.
The answer is
2. 2a+12
Show work
2a+7+2a+7+4+4= 4a+22
A+2+a+2+3+3 = 2a+10
(4a+22)-(2a+10) = 2a+12
Do 77 times 14
770+308=1,078
Divide 1,078 by 100
=10.78

Answer:4
Step-by-step explanation:
Ex (increase, such as taxes or price hike):
I want to increase $5 by 20%.
That means I would have to find the product of $5 and 120%.
$5*1.20=6
If you increase $5 by 20%, you will get $6.
Ex (decrease, such as a discount or a special deal):
I want to decrease $5 by 20%.
That means I would have to find the product of $5 and 80%.
$5*.80=4
If you decrease $5 by 20%, you will get 4.
