Answer:
a = sqrt(2)
Step-by-step explanation:
This is a right triangle so we can use trig functions
sin theta = opp / hyp
sin 30 = a / 2 sqrt(2)
2 sqrt(2) sin 30= a
2 sqrt(2) * 1/2 =a
sqrt(2) =a
Answer:
2 because it holds the same value as -2 and its the additive inverse
Answer:6x^3+16x^2-42x-40
Step-by-step explanation:
To expand
(-2x-8)(-3x^2+4x+5)
6x^3-8x^2-10x+24x^2-32x-40
Collect like terms
6x^3-8x^2+24x^2-10x-32x-40
6x^3+16x^2-42x-40
Answer:
(x+1)(x+1)^2
Step-by-step explanation:
Ok
so paid 16
20% off
original-20%=16
that means the shorts were 100-20=80% of the original cost
percent means parts out of 100
80%=80/100=0.80
16=0.8 of ogirinal cost
'of' means mutpliy
16=0.8 times original
divide both sides by 0.8
16/0.8=ogirinal
20==originall
$20=original price
