REALLY NEED HELP<br><br> Evaluate the following expression.<br><br> (−2.2 )·(−2)·(−14)·(5)

Lisa [10]

Answer:

-308

Step-by-step explanation:

Given that:

=(−2.2 )·(−2)·(−14)·(5)

As "-" sign into "-" becomes "+"
(2.2)(2) = 4.4

=(4.4)*(-14).(5)

As (-14)*(5) = -70

=(4.4)*(-70)

Multiplying 4.4 with -70

= -308

160 + -110 + -3c = -2

jarptica [38.1K]

Steps to solve:

16c - 11c - 3c = -2

~Combine like terms

(16c - 11c - 3c) = -2

5c - 3c = -2

2c = -2

~Divide 2 to both sides

c = -1

Best of Luck!
