A square has 4 equall side so if one side is 2x+3
then:
the perimeter is 2x+3 + 2x+3 + 2x+3 + 2x+3
Combine like terms and the answer is:
8x+12
<span><u><em>The correct answer is: </em></u>
535.
<u><em>Explanation</em></u><span><u><em>: </em></u>
4 hundreds = 4*100=400.
13 tens = 13*10 = 130.
5 ones = 5*1=5.
Together, this gives us 400+130+5=535.</span></span>
Remark
She starts out with x
She spends 10 dollars paying back her brother (that's - 10)
She spends 30 dollars on fuel (that - 30)
She spends 1/2 what's left on a tent ( that's 1/2 (x - 10 - 30) )
She then spent 29.45 on running shoes. 1/2 (x - 10 - 30) + 29.45 is her expenditures.
After all that she has 17.75 left.
Equation
x - 10 - 30 - 1/2(x - 10 - 30) - 29.45 = 17.75
Solve
Begin by adding 29.95 to both sides.
x - 10 - 30 - 1/2(x - 10 - 30) = 17.75 + 29.45
x -10 - 30 - 1/2(x - 10 - 30) = 47.20 Add the like terms on the left.
x - 40 - 1/2(x - 40) = 47.20 Add 40 to both sides. Don't go inside the brackets.
x - 1/2x + 1/2 (40) = 87.20
1/2 x + 20 = 87.20 Subtract 20 from both sides.
1/2 x = 67.20 Multiply by 2
x = 134.40
Answer:
24x³-62x²+49x-12
Step-by-step explanation:
We can start by multiplying the first two brackets together first.
(3x-4)(2x-1)(4x-3) = (6x²-3x-8x+4)(4x-3)
Evaluate like terms.
(6x²-3x-8x+4)(4x-3) = (6x²-11x+4)(4x-3)
Multiply the two brackets together.
(6x²-11x+4)(4x-3) = 24x³-18x²-44x²+33x+16x-12
Simplify.
24x³-18x²-44x²+33x+16x-12 = 24x³-62x²+49x-12
