P = 2d
d = 2n.....n = 1/2d
q = d - 3
since dimes is mentioned in relation to quarters, pennies, and the nickels, u would use d as ur variable
ur expression would be : d + (2d) + (1/2d) + (d - 3) = total amount of coins...then u would solve for d, the number of dimes. And once u know that, u can sub that answer back into ur original equations to find the number of pennies, quarters and nickels
The answer would be c because 1-5-7 is the same as 5-8
Answer:
2x to the second power +x−10
Step-by-step explanation:
Let's simplify step-by-step.
5x+x2−4−(4x−x2+6)
Distribute the Negative Sign:
=5x+x2−4+−1(4x−x2+6)
=5x+x2+−4+−1(4x)+−1(−x2)+(−1)(6)
=5x+x2+−4+−4x+x2+−6
Combine Like Terms:
=5x+x2+−4+−4x+x2+−6
=(x2+x2)+(5x+−4x)+(−4+−6)
=2x2+x+−10
