Answer:
(x + 2)(x + 9)
Step-by-step explanation:
when given a trionomial, you must multiply the last term (18) by the first term's coefficient.
1 * 18 = 18
then, expand the polynomial by finding two factors that SUM to the middle term's coefficient (11) and MULTIPLY to 18. these factors are 9 and 2.
9 * 2 = 18 and 9 + 2 = 11
expand the equation using these
x² + 9x + 2x + 18
factor by grouping
(x² + 9x)(2x + 18)
x(x + 9)2(x + 9)
remove one of the COMMON parenthetical factors (one factor will have an identical factor, in this case (x + 9))
(x + 2)(x + 9) are left.
9 and 250 thousandths written as a mixed number is as much as 9 250/1000. We can simplify it, so we'll get:
9 25/100
Or even:
<u>9 1/4
</u>
I hope it will help you :)
Answer:
The solution is (4, 1).
Step-by-step explanation:
For the first multiply the second equation by -1 then add them together.
4x + y = 5
-1( 3x + y = 3)
4x + y = 5
-3x - y = -3
x=2
Plug that in and you get -3 for y
Answer is (2,-3)
For the second, just add them
2d – e = 7
d + e = 5
3d=12
d=4
Plug that into either equation and e is 1
The solution is (4, 1).
Answer:
I think the larger block has a scale 25 times bigger than the smaller block since 100 divided by 4 equals 25
Please tell me if I'm wrong

Answer:
90, 92, 94, 96
Step-by-step explanation:
Let the three consecutive even integers be x, (x + 2), (x +4) & (x + 6)
Hence, the three consecutive even integers are 90, 92, 94, 96.
