Well, the first step would be to multiply everything out. 1*2=2, g1*i=i, g2i*2=4i, and 2i*i=2i^2. This would bring the equation to 2+i+4i+2i^2=5(2+i)
Next, multiply the other side. 5*2=10, and 5*i=5i. The equation is now:
2+i+4i+2i^2=10+5i
Now, combine like terms, and arrange the sides from highest exponents to lowest exponents: i+4i=5i. You can arrange the equation to 2i^2+5i+2=5i+10.
Subtract 2 from both sides: 2i^2+5i=5i+8
Subtract 5i from both sides: 2i^2=8
Divide both sides by 2: i^2=4.
Finally, find the square root of 4 to get i. The square root of 4 is 2, so i=2.
If you want to round to the nearest thousand, you cannot look at the thousands place to round. You will have to look at the number in the hundreds place. The rules of rounding are
<em>5 and above-round up. Example-2743. 7 is greater than 5, so 2743 rounded to the nearest thousand is 3000.
</em>
<em>4 and below-round down. Example-4390. Three is less than 5, so 4390 rounded to the nearest thousand is 4000.
</em>
Apply these rules to your problem. 8 is greater than 5. So we will round up. You get 5000.<em>

1x2 2x1 67-65 44-42 4-2 all equal positive 2
14*1.5*7= 147 cubic inches (in3)
The third answer.
Answer:
A. 191.54 ft²
B. $2011.17
Step-by-step explanation:
Part A involves multiplying to find the area of the living room using the formula to find the area of a rectangle.
A = b*h (original formula)
A = 15.7*12.2 (substitute values)
A = 191.54 (multiply)
The area of his living room is 191.54 ft²
Next, you need to multiply the number of ft² by the cost per ft² to find the cost to tile the living room
Cost = $10.50*191.54 (equation)
Cost = $2011.17 (multiply)
The total cost of tiling the living room would be $2011.17
