Simplify -2(4 – 5s + 12t – 2u)

g100num [7]

Answer: -8+10s-24t+4u

Steps: Multiply the parantheses by -2

-2×4-2×(-5s)-2×12t-2×(-2u)

Multiply the numbers and calculate the product.

-8+10s-2×12t-2×(-2u) → -8+10s-24t-2×(-2u) → -8+10s-24t+2×2u

And you get -8+10s-24t+4u

Hope this helps ʕ•ᴥ•ʔ

A company that creates steering wheels for cars found that 2 of the steering wheels manufactured each hour yesterday were defect

Ymorist [56]

2 steering wheels manufactured each hour were defected
There were 50 steering wheels manufactured per hour
The fraction is $\frac{2}{50}$
Divide 2, which is the numerator by 50, which is the denominator
2÷50=.04
To change any decimal into a fraction, multiply by 100
The multiply .04 by 100 to change into a percentage
.04×100=4.⇒4%
4% is the percentage of defective steering wheels

Tan 2A + sin 2A=4 tan A/(1 - tan4 A)

stich3 [128]

Answer:

$when \: \\ \tan(2x) = \frac{2 \tan(x) }{1 - {( \tan(x)) }^{2} } \: \: and \\ \sin(2x) = \frac{2 \tan(x) }{1 + {( \tan(x)) }^{2} } \\ then \\ \sin(2x) + \tan(2x) = \frac{2 \tan(x) }{1 - {( \tan(x)) }^{2} } + \frac{2 \tan(x) }{1 + {( \tan(x)) }^{2} } \\ = \frac{2 \tan(x)(1 + {( \tan(x)) }^{2} + 2 \tan(x) (1 - {( \tan(x)) }^{2} }{(1 + {( \ \tan(x)) }^{2}(1 - {( \tan(x)) }^{2} } \\ = \frac{2 \tan(x) \times 2 }{1 - {( \tan(x) }^{4} } \\ = \frac{4 \tan(x) }{1 - {( \tan( \times ) )}^{4} }$
