Answer:

-512

Step-by-step explanation:

The laws of exponents state that multiplying two exponents together of the same base allows you to add the exponents. Raising an exponent to another power allows you to multiply the exponents. In this case. you have (-2)^3*((-2^3))^2. First, you  take the second term, or ((-2^3))^2 and simplify it. Since you're raising an exponent to another exponent you have (-2)^(3*2), or (-2)^6. Now, you multiply by (-2)^3. Since they both have the same base, you can add the exponents to get (-2)^9. Since (-2)^9 is raised to an odd exponent, you know you're answer is going to be negative. 2^9 is 512, so that negative would be -512. If you're looking for an expression for this, you can write (-2)^9

Brook drove a total of 180 miles in 3 hours. Diederick drove a total of 160 miles in 4 hours.
ArbitrLikvidat [17]
Actually, DIEDERICK drove faster than BROOK. What you can do to find out the answer, is divide. Brook drove 180 miles in 3 hours, so divide 180 by 3, and you get 60. If you divide 160 by 4, you get 40. So, that means that Diederick drove faster than Brook.

If 2x = 5, 3y = 4, and 4z = 3, what is the value of 24xyz ?
NISA [10]
2x=5 so 5÷2 = x (2.5)
3y = 4 so 4÷3 = y (1.3 recurring)
4z = 3 so 3÷4 = z (0.75)

implement: 24x2.5x1.3•x0.75

Factorise x squared + 4x + 3 ​
olganol [36]
<h3>Answer:  (x+1)(x+3)</h3>

===================================================

Explanation:

Let's assume it factors into (x+a)(x+b)

The goal is to find the two numbers a and b.

FOIL out (x+a)(x+b) to get x^2+(a+b)x+ab

Note how a+b is the middle term and ab is the last term.

In the original expression, 4 is the middle term and 3 is the last term.

So we need to find two numbers that

  • add to 4
  • multiply to 3

There are two ways to multiply to 3 and they are

  • 1 times 3 = 3
  • -1 times -3 = -3

But only the first way has the factors add to 4. So that means a = 1 and b = 3.

Therefore (x+a)(x+b) = (x+1)(x+3)

And x^2+4x+3 = (x+1)(x+3)
