If 5.6 and 2.1 are the measurements then:
you multiply 5.6 and 2.1 to get the area.
Area=11.76squared
You add 5.6+5.6+2.1+2.1 to get the perimeter.
Perimeter=15.4
First you need to leave the variable by itself.
-4=5n+6
-4-6=5n
-10=5n
n=-2 done!
Answer:
3. 102
4. c
Step-by-step explanation:
For number 3:
(c^2 - a) + b becomes (10^2 - 3) + 5
10^2 = 100
100 - 3 + 5 = 102
For number 4:
Usually when you see distributive property, you're multiplying into parentheses. This time you're factoring out.
20c - 8d
It's not a, because that would be 20c + 8d
It's not b, because that would be 20c -32d
It is c, because 4 x 5c = 20 c and 4 x -2d = -8d
It's not d, because that would be 20c- 8cd
1,925 is close to 2,000
so 2,000 x 7 = 14,000
1,925 x 7 = ?
5 x 7 = 35
20 x 7 = 140
900 x 7 = 6,300
1,000 x 7 = 7,000
so 7,000 + 6,300 + 140 + 35 = 13,475 and 13,475 is close to 14,000 or 13,500 or 13,470.
Hope this helps even though a little confusing! ;D
Answer:
