Algebraic Proof Given: 3w + 4w - 2 = 12 Prove: w = 2

Mathematics
1 answer:
choli [55]3 years ago
4 0

Answer:

Step-by-step explanation:

Replace W with 2

(3 x 2) + (4 x 2) -2 = 12

6 + 8 -2 = 12

add 6 + 8 = 14

14 - 2 = 12

Subract 14 - 2 = 12

which your answer in the end would be 12 = 12

which proves W is 2

Which ratio is equivalent to 3:18?<br> A 6:21<br> B 5:20<br> ( 7:42<br> D 12:2
anzhelika [568]
Answer is C. 7:42
Because the numbers from the ratio 3:18 , 18/3 is 6
And from the ratio 7:42, 42/7 is also 6
Because the difference in the ratios are the same, the ratios are equivalent

Another way is that 3:18 can be rewritten as 3/18 which is simplified to 1/6. 7:42 = 7/42 which also equals 1/6.

Both ratios simplified equal 1:6.
None of the other answers simplify to this but C.

Please factor and find the zeros of each relation (18 marks)
AlekseyPX

Answer:

C. \ \frac{-2}{3} , \ \frac{-4}{5}\\\\D. \ -2, \ -4

Step-by-step explanation:

C.

30x^2 + 44x +16 = 0\\\\2(15x^2 + 22 + 8) = 0\\\\2(15x^2 + 12x + 10x + 8) = 0\\\\2(3x(5x + 4)+2(5x + 4))=0\\\\2((3x + 2)(5x + 4)) = 0\\\\Zeroes : 3x + 2 = 0 => x = \frac{-2}{3}\\

             5x+ 4 = 0 => x = \frac{-4}{5}

D.

10x^2 + 60x +80 = 0\\\\10(x^2 + 6x + 8)= 0\\\\10(x^2 + 4x + 2x + 8)=0\\\\10(x(x+4)+2(x+4))=0\\\\10((x+2)(x+4))=0\\\\Zeroes : x + 2 = 0 =>x = -2

            x + 4 = 0 => x= -4
