2.21 x 10^17 and the answer is 2.21e+17
Answer:
26 + 3 x 42 + 7 x -2 = 138
Step-by-step explanation:
Ok bud, first step we must convert our symbols (Makes it easier to solve)
26 + 3 x 42 + 7 x -2
* subsitutes for multiplication.
I recommend using PEMDAS at times:
1 - Parentheses
2 - Exponents and Roots
3 - Multiplication
4 - Division
5 - Addition
6 - Subtraction
Yet again your numbers were spaced out could they be exponents? if so:
3x^{42}+7x+24
Our answer would round to 24 but he equation was not put in a valid or straight forward way.
Answer:
13 it is very easy
Step-by-step explanation:
(I will do my best to entirely explain the subject) To understand Positives and Negatives you need to have a number line.
<u>-3 -2 -1 0 1 2 3</u>
Your whole life you have been using positives and negatives when you subtract or add a number. 9 - 2 is really just 9 + -2
With the number line it should be easier to understand that for every single time you add or take away you change the value. The more you take away (Negative numbers, 5 + -6) the farther down the value goes to the left, more towards the negative side (5 + -6 = -1). The same goes for addition (-6 + 9 = 3).
To multiply all you need to do is count how many times you see a negative number. If you see an even number of negatives then the answer will be positive because on the number line you went from one side to the other multiple times, left right left right and all that jazz. Hopefully i made this make more sense to you, if there is anything i need to clarify on please make it known so i can edit my answer.
Answer:
2804 cm²
Step-by-step explanation:
<u>Total area comprises of 6 faces: 2 trapezoids and 4 rectangles</u>
- Trapezoid = 1/2*(14+32)*24 = 552 cm² each
- Bottom = 17*32 = 544 cm²
- Top = 14*17 = 238 cm²
- Right side = 17*24 = 408 cm²
- Left side = 17*√((24² + (32-14)²) = 17* √900 = 17*30 = 510 cm²
<u>Total area:</u>
552*2 + 544 + 238 + 408 + 510 = 2804 cm²
