Answer:

C) -3 x2 + 6

Step-by-step explanation:

Given algebraic expressions are:

  • \[2x^{2}+3x-4\]
  • \[8-3x\]
  • \[-5x^{2}+2\]

Adding the given expressions:

\[2x^{2}+3x-4 + 8-3x + (-5x^{2}+2)\]

Simplifying:

\[2x^{2}-5x^{2}+3x-3x-4 + 8 + 2\]

\[= (2-5)x^{2}+(3-3)x+(8 -4 + 2)\]

\[= -3x^{2}+6\]

Among the given options, this is equivalent to option C.

What is the length of the interval of solutions to the inequality 1≤3-4x≤9?
oksian1 [2.3K]

Answer: -3 ≤ x ≤ -1

Step-by-step explanation:

1 ≤ 3 - 4x ≤ 9

1 + 3 ≤ - 4x ≤ 9 + 3; Add 3 on all sides

4 ≤ -4x ≤ 12

1 ≤ -x ≤ 3; Divide 4 on all sides

-1 ≥ x ≥ -3; Multiply -1 on all sides(FYI: When multiplying or dividing negative numbers in inequalities, make sure to reverse the signs as well)

Help plz math question. EXPLAIN HOW YOU GOT THE ANSWER. 30 PTS btw thx if u help
pentagon [3]

Answer:

256

Step-by-step explanation:

4^4^4 = 4^(4^4) = 4^256

so written in base 4, there will be 256 zeroes after a 1.

This translates to approximately 154 digits in decimal.

Just like 2^2^2 =  2^4

there will be four zeroes after a 1.

2^2^2=2^(2^2) = 2^4 = 16 = 10000 (16 in base 2).
