Step-by-step explanation:

perfect square sholud be $(a+b)^{2}$

so (w+3)*(w+3) is perfect square and extention of it is =>w*w+6w+9

In triangle ABC, the measure of ∠B is 90°, BC=16, and AC=20. Triangle DEF is similar to triangle ABC, where vertices D, E, and F

nevsk [136]

The third side of triangle ABC is AB. Using the Pythagorean Theorem, its length is 12.
12² + 16² = 20²

∠F is congruent to ∠C and so the sin(∠F) = sin(∠C)

The sin(∠C) = opposite/hypotenuse
= |AB| / |AC|
= 12/20
= 3/5
= 0.6

Answer:
Yes, it is 0.6

Complete the square to transform the expression x^2+4x 2 into the form a(x − h)2 + k.

faust18 [17]

Answer:

$(x+2)^2-2$

Step-by-step explanation:

we have the expression

$x^2+4x+2$

Convert to vertex form

$a(x-h)^2+k$

where

a is the leading coefficient

(h,k) is the vertex

Complete the square

$(x^2+4x+2^2)+2-2^2$

$(x^2+4x+2^2)-2$

Rewrite as perfect squares

$(x+2)^2-2$

so

The coefficient a =1

The vertex is the point (-2,-2)
