Answer:
1a) 1141/660
3/5 + 6/11 +7/12
find the LCM of the denominators
the LCM of 5,11,12 is 660
after finding the LCM divide it with the denominator.
after dividing 660 by 5 i get 132. So i need to multiply it with 3. Now, i got 396. Do the same with the rest of the numbers.
u will get smth like this: 396+360+385/660
and the final answer will be1141/660.
b) 71/40
c) 211/28
d) 103/20
D. All squares are quadrilaterals. Good luck!<span />

2. The Power of a power property: 
In this case, given:
You need to follow these steps in order to simplify it:
1. Apply the Product of powers property:
2. Apply the Power of a power property:
3. Finally, since 
and 
, you get:
Answer: x = 41.22 and 38.78
Step-by-step explanation:
Given the equation
4x² - 40x + 94 = 0
Using the general formula
x = -b+/-√b²-4ac/2a
Where a = 4, b= -40 c= 94
x = -(-40)+/-√(-40)²-4(4)(94)/2(4)
x = 40+/-√1600-1504/8
x = 40 +/-√96/8
x = 40 +/-9.8/8
x = 40+/-1.22
x= 40+2.22 = 41.22
and x = 40 -1.22
x = 38.78
Answer: 13.
Look at the height and the x. The measurements look very similar, and since the height= 12, 13 is the closest answer to 12 out of the three given answers, so 13 is the value of x.
