Mathematics
1 answer:
Westkost [7]2 years ago
8 0

Answer:

This alot but ill help you with 2 of them to learn em

Step-by-step explanation:

1) 2x^2 +5 =167

Subtract the 5 from both sides to get the equation 2x² = 162

Then divide the 2 from both sides to get x² = 81, Then square root from both sides to get x= 9

6) 2(2y +4)²=72

Divide 2 from both sides to get (2y+4)²=36

Then square root that to get 2y+4 = 6

subtract 4 from both sides to get 2y =2

Then divide both sides from 2. Y=2

P = nc - e and p is 4520 and n is 3000 and e is 700 what is the value of c
adoni [48]

Answer:

c= 1.74

Step-by-step explanation:

4520 = 3000(c)-700

4520=3000c-700

+700             +700

5220=3000c

c=1.74

to check to see if this is right you would do this:

4520=3000(1.74)-700

4520=5220-700

4520=4520

HEYYYY NOBODY ANSWER MY MATH QUESTION I ASK THIS MORNING THAT'S NOT FAIR!!!
Leviafan [203]

Answer:

( a+b) (a-b)

x^2 - 50

Step-by-step explanation:

The formula for difference of squares is

a^2 - b^2 = ( a+b) (a-b)

121x^2 -144 = (11x)^2 - 12^2 so this is the difference of squares

x^2 - 16y^2 = (x)^2 - (4y)^2  so this is the difference of squares

9x^2 -64 = (3x)^2-8^2  so this is the difference of squares

x^2 - 50 = (x)^2 - 2*(5)^2  this is not the difference of squares
