The equivalent of the expression [ (z−3)4z−6 ] is 4z² - 12z - 6.
<h3>What is the equivalent of the expression?</h3>
Given the expression; (z−3)4z−6
First, we apply distributive property.
(z−3)4z−6
(z−3)4z−6
z(4z) - 3(4z) - 6
We remove the parentheses
4z² - 12z - 6
Therefore, the equivalent of the expression [ (z−3)4z−6 ] is 4z² - 12z - 6.

I think it’s 220m. Since 5 rounds are equal to 1100m then you divide by 5 to see how much he covers in one
Answer:
A) 49x^2-36 km
Step-by-step explanation:
Remember that speed is equal to distance divided by time. Therefore, if you multiply time with speed, then you get the distance traveled.
So, we will do (7x+6) kph multiplied by (7x-6) hours to get 49x^2-36 km.
Answer:
5x^4-24x^3-55/x^2

I have the solution in my notes but it's too long✌️
Answer:
n = -3
Step-by-step explanation:
The difference of the square of a number and 24 is equal to 5 times that number. Find the negative solution.
I'm going to call the number "n."
n² - 24 = 5n subtract 5n from both sides to get the equation equal to zero
- 5n -5n
n² - 5n - 24 = 0 factor the trinomial into the multiplicatin of two binomials
we need factors (numbers that multiply) to -24 that add up to
-5. The only factors for -24 that will add up to -5 are -8 and 3.
(n-8)(n+3) = 0 set each binomial equal to zero and solve for n
n-8 = 0 or n+3 = 0
+8 +8 -3 -3
n = 8 or n = -3 n = -3 is the negative solution
