Tbh i dont really remember how to this this but the only way i could think of solving it is saying how a spuare/rectangle have all equal sides so if they have all equal sides you can divide that number by 4 so 4/30=7.5 so i would say x = 7.5 tell me if its wrong
~ Good Luck :D ~
(3x2-11x-4)-(x-2)(2x+3)
Final result :
x2 - 10x + 2
Step by step solution :
Step 1 :
Equation at the end of step 1 :
(((3•(x2))-11x)-4)-(x-2)•(2x+3)
Step 2 :
Equation at the end of step 2 :
((3x2 - 11x) - 4) - (x - 2) • (2x + 3)
Step 3 :
Trying to factor by splitting the middle term
3.1 Factoring x2-10x+2
The first term is, x2 its coefficient is 1 .
The middle term is, -10x its coefficient is -10 .
The last term, "the constant", is +2
Step-1 : Multiply the coefficient of the first term by the constant 1 • 2 = 2
Step-2 : Find two factors of 2 whose sum equals the coefficient of the middle term, which is -10 .
-2 + -1 = -3
-1 + -2 = -3
1 + 2 = 3
2 + 1 = 3
Observation : No two such factors can be found !!
Conclusion : Trinomial can not be factored
Final result :
x2 - 10x + 2
1st Answer:
$25
Step-by-step explanation:
You have to subtract the installation fee from the total fee.
685-85=600
If it is for 2 years, that is 24 months, so divide
600/24=$25
2nd Answer:
36 and 37
Step-by-step explanation:
Consecutive means they fall directly next to each other EX: 1, 2, 3, 4.... are consecutive numbers
36 and 37 are consecutive
36+37=73

Answer:
(2, 1).
Step-by-step explanation:
f(x)=2x^2-8x+9
Find -b/2a first, it's -(-8)/2(2)=8/4=2.
Then find the y-coordinate of the vertex.
2(2)^2-8(2)+9=2(4)-16+9=8-16+9=-8+9=1
