Which facts could be applied to simplify this expression? Check all that apply. 5x + 3y +(-x) + 6z 1. To add like terms, add the coefficients, not the variables.
2. First add 5x + x.
3. The simplified expression is 4 x + 3 y + 6 z.
4. Only combine terms that contain the same variable.
5. The simplified expression is 5 x + 3 y + 6 z

13

step-by-step explanation:

169-1=168

168-3=165

165-5=160

160-7=153

153-9=144

144-11=133

133-13=120

120-15=105

105-17=88

88-19=69

69-21=48

48-23=25

25-25=0

since it took 13times to completely subtract it hence its square root is 13

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2

mean, 40.6
