For this question, we must use BIDMAS
Brackets
Indices
Division
Multiplication
Addition
Subtraction
26.6 x 24.4 / 5.67 x 4.02
First, round all the values to their first significant figure
30 x 20 / 6 x 4
The first occurring operation in BIDMAS is Division
20/6 = 3 1/3
Now do the multiplication
30 x 3 1/3 x 4 = 400
Or you can round to the nearest whole number (although it can be more difficult if doing sums in your head)
27 x 24 / 6 x 4
27 x 4 x 4
27 x 16 = 432
The more accurately you round, the closer the estimation is to the actual answer (≈460)
1 Sig Fig = 400
Whole number = 432
I hope this is correct
Simplifying (2x + -1)(x + -3) = 18 Reorder the terms: (-1 + 2x)(x + -3) = 18 Reorder the terms: (-1 + 2x)(-3 + x) = 18 Multiply (-1 + 2x) * (-3 + x) (-1(-3 + x) + 2x * (-3 + x)) = 18 ((-3 * -1 + x * -1) + 2x * (-3 + x)) = 18 ((3 + -1x) + 2x * (-3 + x)) = 18 (3 + -1x + (-3 * 2x + x * 2x)) = 18 (3 + -1x + (-6x + 2x2)) = 18 Combine like terms: -1x + -6x = -7x (3 + -7x + 2x2) = 18 Solving 3 + -7x + 2x2 = 18 Solving for variable 'x'. Reorder the terms: 3 + -18 + -7x + 2x2 = 18 + -18 Combine like terms: 3 + -18 = -15 -15 + -7x + 2x2 = 18 + -18 Combine like terms: 18 + -18 = 0 -15 + -7x + 2x2 = 0 Factor a trinomial. (-3 + -2x)(5 + -1x) = 0
It depends you mean per day or if so..... it is 720
Same thing as 7 times 5 which is 35.
Answer:
S. 4
M. 2
S. 5
M. 8
And the graphing you just do those as m/s -->(M,S)
