what is the exact value for the expression Square root 56 - Square root 14 + Square root 126 ? simplify if possible

Tasya [4]

$\sqrt{56} - \sqrt{14} + \sqrt{126} = \sqrt{4\cdot14} - \sqrt{14} + \sqrt{9\cdot14} =\\=2 \sqrt{14} - \sqrt{14} +3 \sqrt{14} =2 \sqrt{14} - 1\sqrt{14} +3 \sqrt{14} =4 \sqrt{14}$

Given the function f(x) = 4(x+3) − 5, solve for the inverse function when x = 3.

natulia [17]

$f(x)=4(x+3)-5 \\ f(x)=4x+12-5 \\ f(x)=4x+7 \\ \\
\hbox{solve for x:} \\
y=4x+7 \\
y-7=4x \\
x=\frac{y-7}{4} \\ \\
\hbox{swap x and y:} \\
y=\frac{x-7}{4} \\ \\
f^{-1}(x)=\frac{x-7}{4} \\
f^{-1}(3)=\frac{3-7}{4}=\frac{-4}{4}=-1 \\
\boxed{f^{-1}(3)=-1}$

Practice Question 2 - Find the Volume

Brrunno [24]

Answer:

112.896

Step-by-step explanation:

To calculate the volume of a triangular prism, measure the width and height of a triangular base, then multiply the base by the height by 1/2 to determine the triangle's area. Next, measure the height of the triangular prism and multiply this by the triangle's area to get the volume.
