Which expression is equivalent to 3 ( x + 10)

devlian [24]

Answer:

3x + 30

Step-by-step explanation:

$3(x+10)\\\\\text{Distribute '3' into 'x + 10'}\\\\\\3(x+10)\rightarrow3x+30\\\\\left \{ {{3*x=3x} \atop {3*10=30}} \right.$

3x + 30 would be an equivalent expression.

V = pi r^2 d

Divide each side by pi r^2

V/(pi r^2) = pi r^2 d/(pi r^2)

V/(pi r^2) = d

Then substitute the values into the equation to find d

The base of a triangle exceeds the height by 6 cm if the area is 260 cm² find the length of the base and the height of the trian

N76 [4]

$Let \: the \: base \: be \: x, \: the \: height \: would \: be: \:x-6\\The \: area \: is: \:$

$\frac{x(x - 6)}{2} = 260 \\ {x}^{2} - 6x = 520 \\ {x}^{2} - 6x - 520 = 0 \\ (x + 20)(x - 26) = 0 \\x = 26$
