For the first equation n + 4 = 5, because 0 + 4 is not equal 5
Answer:
5, 48, 4, 32, 3, 24
Step-by-step explanation:
do not get intimidated by this question , its very easy
let's break it ike this, 543 x 18
get the bigger number first , 543
each digit will be multiply by the opposite number which it's 18
READY? watch! 543 ( we'll separate them)
1. 5x (18) we'll break the 18 watch. 1 and 8 and we'll multiply each by 5
<u>5</u>x1= 5
5x8= 48.
2. 4x 18
<u>4</u>x1=4
4x8=32
3. <u>3</u>x 18
3x1=3
3x8= 24
Answer: 
Solving for variable x
Move all terms containing x to the left, all other terms to the right
<u>Add -17 to each side of the equation</u>
<u></u>
<u></u>
<u></u>
<u>Combine like terms: 17 + -17 = 0
</u>
<u></u>
<u></u>
<u></u>
<u>Combine like terms: -3 + -17 = -20</u>
<u></u>
<u></u>
<u></u>
<u>Divide each side by 2</u>
<u></u>
<u></u>
Combine like terms
a^2-4a^2=-3a^2
7a^3+11a^3=18a^3
Then put them back together from greatest exponent to smallest exponent
18^3-3a^2-a
