Divide each term by −5 and simplify. t ≤ −14. So A. should be the correct answer.
Sec^2 x - 1 = tan^2x
Proof:
Sec^2x = 1+ tan^2x
1/cos^2x = 1 + sin^2x/cos^2x
<span>1/cos^2x - sin^2x/cos^2x = 1
</span>Using common denominator:
(1-sin^2x)/cos^2x = 1
sin^2x + cos^2 x = 1
cos^2 x = 1 - sin^2x
Substituting :
cos^2x/<span>cos^2x = 1
</span>1 = 1
Left hand side = right hand side
Answer:
20/3
Step-by-step
(base1+base2)/2 * height = area of a trapezoid
64/12=16/3
16/3*2 = 32/3
32/3-4 = 20/3

Answer:
3(50 g) = 150 g
Step-by-step explanation:
If you mean 25% sugar by mass, then 1/4 of the total mass is sugar, and 3/4 is water. So you need 3 times as much water as sugar.
3(50 g) = 150 g
