Which expression is equivalent to the given expression? 12(x – 17)
12 * x 12 * (-17) multiply 12*x and 12 * (-17)
what about like 5 more please
what expression is equivalent to the given expression? 13x – 29x
Subtract like terms, 13 - 29 = -16 So, -16x
\[a(b-c)=ab-ac\]\[a(b+c)=ab+ac\]\[(a^5)~^6=a^{5+6}=a^{11}\]\[a^{-b}=1/a^b\]\[7x-4x=(7-4)x=3x\]\[8d+4d=(8+4)d=12d\]\[a^7/a^3=a^{7-3}=a^4\]more tips?
that was so confusing
Those are rules lol, some are exponent, others are distributive property etc. you'll learn about those later on.
Evaluate the expression, using the given value of the variable. 2 – 8x + 3x when x = 5
i reallyneed to pass this thing can u please help me
8(5) + 3(5) 40 + 15 - 2 = ?
53??
\[Evaluate~~~~~the~~~~~expression,~~~~~using~~~~~the~~~~~given~~~~~value\]\[of~~~~~the~~~~~variable.\]\[5+11x-6x~~~~~~~~~~~~~~~~~~~~~when~~~~~~~x=2\]\[5+11(2)-6(2)\]\[5+22-12\]\[15\]can you do your problem now?
Yup .. @SolomonZelman lol you're value is incorrect
Evaluate the expression, using the given value of the variable. z ÷ 4 – 8z + 2(z – 5) when z = 12
Ohh thats different nvm sorry >.>
so it was 53
Plug in 12 for z in your expression @ala
you tagged someone else, @tHe_FiZiCx99
12 / 4 - 8(12) + 2(12 - 5)
lol #Fail >.>
so or 8z woule i multiply 8 and 12 or divide them
for*
??
Yes, plug in 12 in the equation.. 12 / 4 - 8(12) + 2(12 - 5)
so its ether 79 or 74 right??
-79*
Combine like terms. 7k – 13k
They're both the same.. just subtract 7 - 13 = ??
6
or -6
No... 7 MINUS 13 .. its negative. You have $7 and you have to pay 13.. your in debt. Also negative. <- Example..
