Answer: 6•12 ÷ √36 -4 ÷2+(8-5) = -21
Step-by-step explanation:it's -33 because PEMDAS first perenthese 8 - 5 = 3 then exponents the square root of 36 is 6 then multiply and divide left to right we can multiply 6 times 12 which equals 72, then we divide 72 ÷ 6 = 12 and 12 • -4 = -48 and -48 ÷ 2 = -24 and then we add and subtract left to right -24 + 3 = -21, So the answer is -21.
Answer:
3x³ + 12x
Step-by-step explanation:
3x is 3 times x. If we multiply x times x², we get x³. This is because x² can be written as x·x, so if we multiply x by that, we get x·x·x. Since we are multiplying x² by 3x, we get 3x³. Now, we multiply 3x by 4, this gets us 12x. Now, we write it out as 3x³ + 12x.
