I'm pretty sure its 100 because if she gave each of her 19 students 5 invitations that equals 95. (19×5=95) And She had 5 leftover equals 100. (95+5=100)

Solve by completing the square<br> -x^2+8x-6=0
Svetllana [295]
-x² + 8x - 6 = 0
x = <u>-(8) +/- √((8)² - 4(-1)(-6))</u>
                     2(-1)
x = <u>-8 +/- √(64 - 20)</u>
                 -2
x = <u>-8 +/- √(44)
</u>              -2<u>
</u>x = <u>-8 +/- 2√(11)
</u>              -2
x = <u>-8 + 2√(11)</u>         x = <u>-8 - 2√(11)
</u>             -2                            -2<u>
</u>x = 4 - √(11)             x = -8 + √(11)

Which of these expressions CANNOT be simplified by combining like terms?
densk [106]
5ab^{3} +7-3a^{2} b ^{2} +a^{3}b+10 can be simplified to by adding the 7 and 10 to get a^{3}b-3a^{2} b ^{2}+ 5ab^{3} + 17.

5ab^{3}+3a^{2}b^{2}+a^{3}b -10 cannot be simplified any more by combining like terms.

By distributing the 2b into the parentheses, you can simplify the expression:
5ab^{3}+2b(3ab^{2})+a^{3}b-10\\&#10;5ab^{3}+6ab^{3}+a^{3}b-10\\&#10;11ab^{3}+a^{3}b-10

Here you can just add:
5a^{3}b^{3}+3a^{2}b^{2}+a^{3}b^{3}-10ab\\&#10;6a^{3}b^{3}+3a^{2}b^{2}-10ab

Thus, the only expression that cannot simplify any more using adding like terms is the second, 5ab^{3}+3a^{2}b^{2}+a^{3}b -10.

(9-4) + 3•8 = 29

Explanation

First you need to apply the PEMDAS rule

Parentheses
Exponents
Multiplication
Division
Addition
Subtract

So when solving the problem you first have to solve what’s in Parentheses first. So (9-4) which would equal 5

Next, according to the PEMDAS rule you’d have to do multiplication next. So 3•8 is equal to 24

And finally, the last step is Addition. After you’ve done the Parentheses and Multiplication you have to add up your answers. 5+24 would be 29

Answer= 29
