Answer:
100% equals to 1 because 75% = 0.75 so then just add 25% = 0.25 so 0.25+0.75=1
Step-by-step explanation:
Answer:
a-b = 31 (a ≠ b)
Step-by-step explanation:
(3x²-x+1)(px²+qx+1) = ax⁴+bx³+12x² - 6x + 1
3px⁴+(3q-p)x³+(3+p-q)x²+(q-1)x+1 = ax⁴+bx³+12x² - 6x + 1
q-1 = -6 q = -5
3+p-q = 3+p-(-5) = 8+p = 12 p = 4
b = 3q-p = 3*(-5) - 4 = <u>-19</u>
a = 3p = 3*4 = <u>12</u>
a-b = 12 - (-19) = 31

length : 2x
width : 3x+2
Perimeter = 2(l+w)
substitute in knowns
74 = 2(2x+3x+2)
combine like terms
74 = 2(5x+2)
distribute
74 = 10x+4
subtract 4 from each side
70 = 10x
divide by 10
x=7
Answer x=10
