Answer:
1 centimet
Step-by-step explanation:
Take out the GCF
5(2x^2+3x-14)
Use slip and slide for the inner trinomial
x^2+3x-28
(x+7)(x-4)
(x+7/2)(x-4/2)
(2x+7)(x-2)
Final answer: 5(2x+7)(x-2)
Answer:
(7, -4.5)
Step-by-step explanation:
25−x=−4y ---> x=25+4y
3x−2y=30
use x to substitute into the second equation
3 (25+4y)-2y = 30
75+12y-2y=30
75+10y=30
10y=-45
y=-4.5
3x-2(-4.5)=30
3x+9=30
3x=21
x=7
check:
25-7=-4*-4.5
18=18 (yes)
3*7-2*-4.5=30
21+9=30
30=30 (yes)
