Answer:
C)
Step-by-step explanation:
First use distributive property: a(b +c) =a*b +a*c
-3x + 5(x +2) = -3x + 5*x +5*2
= -3x + 5x + 10 {Combine like terms}
= 2x + 10
(-3x) and 5x are like terms
What did you misspell something for are you foreign
Pyhtaorean theorem says a² + b² = c²
a² + 7² = 25²
a² + 49 = 625; subtract 49 from both sides
a² = 576; square root both sides
a = 24
The perimeter is the distance around the figure, so 7 + 24 + 25 or 56
Answer:
B
Step-by-step explanation:
We know that
cos A = adjacent / hypotenuse
sin A = opposite / hypotenuse
Therefore, sin A / cos A =
(opposite / hypotenuse) / (adjacent / hypotenuse)
= (opposite/hypotenuse) * (hypotenuse / adjacent)
= opposite / adjacent
= tan A
Therefore, tan A = sin A / cos A = y/x
