The product of 2 more than 3 times a number and 6 less than 4 times the number (z)
Rom4ik [11]

Answer:

12z^{2} -10z -12

Step-by-step explanation:

Let the number be z

2 more than 3 times z ==> 3z + 2

6 less than 4 times z ==> 4z - 6

Product of the above two is
(3z + 2) (4z - 6) \\= (3z)(4z) + (3z)(-6) + (4z)(2) + (2)(-6)\\= 12z^{2} -18z + 8z - 12\\= 12z^{2} -10z -12

A jet flies at a rate of 1.3x10^3 feet per hour . Written in scientific notation which is the best estimate of how many feet the
vichka [17]

Answer:

3 * 10^6 if the answer is 3.64 * 10^6, you really ought to argue the meaning of estimate with your instructor.

Step-by-step explanation:

This is a very valuable question. Put your calculator away when you answer it. Using a calculator is sort of cheating.

1.3 * 10^3 roughly is roughly 1 * 10^3

2.8*10^3 hours is roughly 3 * 10^3

Forget the powers for now and just work with the 1 and 3

1*3 equals 3.

10^3 * 10^3 = 10^6 when the base of two numbers is the same (10 in this case) then the powers are added.

10^(3 + 3) = 10^6

So the answer is roughly 3*10^6

Now you can take out your calculator and get the answer.

1.3*10^3 * 2.8 * 10^3 = 3.64 * 10 ^ 6

Notice that the estimate (done in my head) is close enough to tell you what the answer should be. On a test, that's a very handy skill.

lions [1.4K]

\text{Hello there! :)}

\huge\boxed{x = 22.5}\text{Since we know that DE and AC are parallel,}\\\\\text{We can use the Alternate-exterior angle congruency to determine the value of "x":}\\\\6x = 2x + \text{ The supplement of 4, therefore:}\\\\6x = 2x + 180 - 4x\\\\\text{Isolate the "x" variable by adding 4x and subtracting 2x from both sides:}\\\\8x = 180\\\\\text{Divide both sides by 8:}\\\\\boxed{x = 22.5}
