Can somebody help me with this question ?? :)
S_A_V [24]

Answer:

x = 44°

Step-by-step explanation:

Since this is an isosceles triangle, the other angle that isn't defined is also 68°. So, since all the angles add up to 180°,

x + 68(2) = 180

x + 136 = 180

x = 44°

Simplify 7 log3 k + 6 log3 m − 9 log3 n
kaheart [24]
 The answer is log3 k to the seventh power m to the sixth power over n to the ninth power

a * logₓ(y) = logₓ(yᵃ)
7 log₃ (k) = log₃ (k⁷)
6 log₃ (m) = log₃ (m⁶)
9 log₃ (n) = log₃ (n⁹)

7 log₃ (k) + 6 log₃ (m) - 9 log₃ (n) = log₃ (k⁷) + log₃ (m⁶) - log₃ (n⁹)

logₓ(y) + logₓ(z) = logₓ(y * z)
log₃ (k⁷) + log₃ (m⁶) - log₃ (n⁹) = log₃ (k⁷ * m⁶) - log₃ (n⁹)

logₓ(y) - logₓ(z) = logₓ(y / z)
log₃ (k⁷ * m⁶) - log₃ (n⁹) =  log₃ (k⁷ * m⁶ / n⁹)

The formula for the surface area, S, of a cylinder, is S = 2tr2 + 2trh, where h is
kykrilka [37]

Answer:

H = 2        S = 50    A = 50.2

Step-by-step explanation:

A=2πrh+2πr2

S = 2tr2 + 2trh

S = 2 (t x r) + (h x 2t) x r   Try out ^2 for Radius

S = 2t x r^2 + r x h x 2t  Rearrange back and cross out for square^2

S = 6t x 4 + 6t x r x h Cross out for t

S = 6 x 4 + 6 x 2 x h  Balance out...

S= 24 + 12 x 2    Find h = 2

S = 36 + 24

S=  50 sq2

A = 50. 2

R = 2

H = 2  

Checker

Area = 6.28318530718 x 4 + 6.28318530718  x 2 x 2 = 50.27sq2

goldenfox [79]

Answer:

\boxed{ \bold{ \huge{ \boxed{ \sf{ - 2x + 28}}}}}

Step-by-step explanation:

\sf{2x + 4(7 - x)}

Distribute 4 through the parentheses

\dashrightarrow{ \sf{2x + 28 - 4x}}

Collect like terms

\dashrightarrow{ \sf{2x - 4x + 28}}

\dashrightarrow{ \sf{ - 2x + 28}}

Hope I helped!

Best regards! :D
