Not sure why it is a word problem? 13 x 42 = 546
12 x 2 = 42 14 x 3 = 42 7 x 6 = 42 6 x 7 = 42 2 x 12 = 42 3 x 14 = 42
6 x 7 = 4242 - 13 = 29Check:13 + 29 = 42
13 + 42 = 55
6
-55
x-29 = 13+2x x-2x = 13+29 -x = 42 x = -42
13, 14, 15 13 + 14 + 15 = 42 Solution: Let the numbers be x, x+1 and x+2. So their sum is 3x+3 which is said to be 42. Hence x = 13
13 ft x 42 ft = 546 sq ft
The way to approach this is to write a algebraic equation: 13 - (x/7) = 6 Times both sides by 7 which gives: 13 - x = 42 Take away 13 on both sides which gives: -x = 29 x = -29 Now to check it 13 - - 29 = 42 (two negatives make a positive 42 divided by 7 = 6
The GCF of 42 and 273 is 21. 42 = 2 x 21 273 = 13 x 21
42
x + (x+1) + (x+2) ≥ 42 3x + 3 ≥ 42 3x ≥ 39 x ≥ 13 so the integers must be 13, 14, 15 or any other set of consecutive integers where the smallest is greater than 13 (such as 17, 18, 19 or 231, 232, 233)
x+(x+1)+(x+2)=42 3x+3+42 3x=45 x=15 x+1=15 x=14 x+2=15 x+13 so the three consecutive numbers are 13,14, and 15
The easiest way to factor x2 + 13x + 42 is to look at the last number. The last number is 42. Now, think of what whole numbers you can multiply to equal 42. 1 x 42 2 x 21 3 x 14 6 x 7 If you look at the equation, we notice that the sign pattern is + + + When the sign pattern is + + +, we know that whatever two factors you choose must add up to the middle number, 13. So, automatically we can get rid of some of these factors. 1 x 42 --> 1 + 42 doesn't equal 13 2 x 21 --> 2 + 21 doesn't equal 13 3 x 14 --> 3 + 14 doesn't equal 13 Now, we're automatically left with 6 x 7. So, your answer would be (factored out), (x+6)(x+7) Where x = -7, -6
44 = 22 x 11 63 = 32 x 7
