Answer:
1440
Step-by-step explanation:
3(x+4)(x+1)(x+2)(x-2)
Let x= 4
3(4+4)(4+1)(4+2)(4-2)
Evaluate each parentheses
3 ( 8) (5)( 6) (2)
Multiply
1440
If you meant
3(x+4)(x+1)
= 3(4+4)(4+1) = 3 * 8 *5 = 120
(x+2)(x-2)=(4+2)(4-2) = 6 *2= 12
21% is the probability of both of them being red
18. Make the values have the same denominators.
4 2/3(8/8)= 112/24
5 3/8 (3/3)= 129/24
Add the values
112/24+129/24= 241/24
Simplify the answer
241/24= 10 1/24
The answer for question 10 1/24 ounces.
20. Multiply 1 1/4 by 5. (There are 5 days from Monday through Friday)
1.25(5)= 6 1/4
The answer to question 20 is 6 1/4.
Hope this helps!
X=hours master worked
y=hours apprentice worked
62x+40y=492
if master worked 3hours more than apprntice
x=3+y
sub 3+y for x
62(3+y)+40y=492
expand
186+62y+49y=492
186+102y=492
minus 186 both sides
102y=306
divide both sides by 102
y=3
sub back
x=3+y
x=3+3
x=6
master electrician worked 6 hours
6*62=372
master electrician earned $372
It would take you 15 minutes
