What is the factored form of -4/5(30x - 40) + (42x + 4)? ​

18(x + 2)

Step-by-step explanation:

-4/5 ( 30x -  40) + (42x + 4) = -24x + 32 + 42x + 4 = 18x + 36 = 18(x + 2)

18x+36

Step-by-step explanation:

1. Simplify  \frac{4}{5}(30x-40)54(30x−40)  to  \frac{4(30x-40)}{5}54(30x−40).

-\frac{4(30x-40)}{5}+42x+4−54(30x−40)+42x+4

2. Factor out the common term 1010.

-\frac{4\times 10(3x-4)}{5}+42x+4−54×10(3x−4)+42x+4

3. Simplify  4\times 10(3x-4)4×10(3x−4)  to  40(3x-4)40(3x−4).

-\frac{40(3x-4)}{5}+42x+4−540(3x−4)+42x+4

4. Simplify  \frac{40(3x-4)}{5}540(3x−4)  to  8(3x-4)8(3x−4).

-8(3x-4)+42x+4−8(3x−4)+42x+4

5. Expand by distributing terms.

-(24x-32)+42x+4−(24x−32)+42x+4

6. Remove parentheses.

-24x+32+42x+4−24x+32+42x+4

7. Collect like terms.

(-24x+42x)+(32+4)(−24x+42x)+(32+4)

8. Simplify.

18x+3618x+36

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)
