Answer:
9x + 5y + 11
Step-by-step explanation:
3x + 4y + y - 2x + 11 + 8x
Group like terms
(3x - 2x + 8x) + (4y + y) + 11
Combine like terms
9x + 5y + 11
X=36
you add 126 to 162 making it 288, then you minus 5 out of 13 making it 8. 288/8 =36
6.4 x 10^3 = 6400
1.4 x 10^4 = 14000
7.5 x 10^3 = 7500
total = 6400 + 14,000 + 7500
total = 27900 or 2.79 x 10^4 <===
first the square root of 4 is 2 so we can sub that in.
now we have 2(2*2)^-2.
2 * 2 of course is 4
with 2(4)^-2, keep in mind that negative exponents just mean to "flip" the number and turn the exponents positive.
so 4^-2 is the same as 1/4^2 or 1/16.
finally 1/16 * 2 = 2/16. 2/16 simplified is 1/8.
