Step-by-step explanation:
a)i) perimeter= side+side+side+side
perimeter=8.7+8.7+5.4+5.4=28.2cm
ii) area=h×b
area=8.7×5.4=46.98cm²
b)i) perimeter=20.35+20.35+17.84+17.84
perimeter=76.38cm
ii)area=20.35×17.84
area=363.044cm²
c) area of rectangular field=937.125m²
Length=36.75m
i)Breadth=937.125÷36.75=25.5m
ii)perimeter=36.75+36.75+25.5+25.5
perimeter=124.5m
The absolute value of -5 is 5 (absolute value being how many units to 0)
So we really have 5 - 45 ÷ 3 =
Order of operation says to do the division first (there are no parentheses or exponents). So now we have 5 - 15= and the answer to that is -10.
Parallel lines are two lines that are not crossing each other for instance \\ that is a parole line
Answer:
6x^3-5x^2-8x+3
Step-by-step explanation:
(2x-3)(3x^2+2x-1)
6x^3+4x^2-2x-9x^2-6x+3
6x^3+4x^2-9x^2-2x-6x+3
6x^3-5x^2-8x+3
4k-36 = 9k-44
add 36 to both sides:
4k =9k-8
subtract 9k from each side
-5k=-8
k = -8 / -5 = 8/5
