It looks like the length of a and b should be the same. You can use the Pythagorean theorem (only works with right triangles):

a² + b² = c² (c is the hypotenuse or the longest side of the triangle, a and b are the other side lengths of the triangle)

a² + (4)² = (5)²

a² + 16 = 25

a² = 9

a = 3

a and b have a length of 3

Which expression can be written as k square root 3 where k is an integer

Damm [24]

Answer:

A simple expression is $\sqrt{48}$ = 4 $\sqrt{3}$

Step-by-step explanation:

Surds are irrational numbers expressed with respect to a square root. There are some basic rules required when dealing with surd.

Integers are numbers that do not have a decimal or fractional part i.e whole numbers. So, a simple expression that can be written as k square root 3 where k is an integer is $\sqrt{48}$ .

So that,

$\sqrt{48}$ = $\sqrt{16 * 3}$

= 4 $\sqrt{3}$

For f(x) = x2 + 2x + 3, and g(x) = x2 + 5, Find F(g(2)).

Paraphin [41]

Answer:

f(g(2)) = 102

Step-by-step explanation:

f(x) and f(g(2))

As we can see, we can find g(2) and substitute this value into

f(x)=x² + 2x + 3 instead of x.

g(x) = x² + 5, g(2) = 2² + 5 = 9

f(x)=x² + 2x + 3

f(9)=9² + 2*9 + 3= 102
