Here, we want to get what Andre's mistake was and correct it
To answer this, we are supposed to use the division law of indices
We have this as;
Now, in the case of this question, x is 4 and y is -3
So, we have the expression as;
His mistake is thus adding the exponents instead of subtracting
Answer: D
Step-by-step explanation: |-9| = 9 and |8| = 8 so 9 is greater than 8
Answer:
730 Is right I hope it was
Step-by-step explanation:
Answer:
X=14
Explanation:
The question tells us that the triangle is an equilateral triangle, meaning all of its side lengths are equal.
The perimeter of the triangle is all the lengths added together, so we can say this:
Perimeter=3(1.75x-2)
And since the question tells us the perimeter, we can input that into the equation as well.
67.5= 3(1.75x-2)
And now we solve:
67.5= 3(1.75x-2)
Distribute 3 into the parentheses
67.5=5.25x-6
Combine like terms (move -6 to the other side)
67.6+6=5.25x
73.6=5.25x
Divide both sides by 5.25
73.6/5.25=5.25x/5.25
14=x
I hope this helps! Please comment if you have any questions.
Answer:
42-24n
Step-by-step explanation:
(7 - 4n) . 6
= (7)(6) - (4n)(6) ...........using distributive property, multiply each term by (6)
= 42 -24n (answer)
