Find the missing factor.<br> 7s^2 + + 13s + 6 = (7s + 6)<br> )
Anton [14]

Answer:

71s

Step-by-step explanation:

The question we have at hand is 7s² + ___ + 13s + 6² = (7s + 6)². We can expand the perfect equation " (7s + 6)² " in order to find our solution. A perfect square consists of 3 terms, and hence the term in the blanks must add to 13s to form another term.

Applying the perfect square formula : ( a + b )² = a² + 2ab + b², let's expand the expression,

(7s + 6)² = ( 7s )² + 2( 7s )( 6 ) + ( 6 )² =  7s² + 84s + 6²

84s - 13s = 71s, which fills in the blank provided.

Sin155° = _____ sin25° sin(-25)° -sin25°
patriot [66]

Answer:

sin 25

Step-by-step explanation:

sin(A − B) = sinA cosB − cosA sinB

sin 155

sin( 180 -25)

A = 180  B = 25

sin180 cos25 − cos180 sin25

Sin 180 = 0

cos 180 = -1

0 - (-1) sin 25

sin 25
