How do you factor 4s2-9?
4s2 - 9 can be expressed by using the identity: a2 - b2 = (a-b)(a+b) Therefore, 4s2 - 9 = (2s)2 - 32 = (2s-3)(2s+3)
Can you make 9 using only four 2s?
Yes
Is it possible to get 10 using 3 2s?
no.
How do you get 2 using four 2s?
2+ (2-2)x2 = 2
Is it possible to get 22 using four 2s?
Yes. It's 22 x 2 ÷ 2
How can i use four 2s and one 3 to make 50?
3 x (22)2 + 2 = 50
Can you make 11 using only four 2s?
Yes, you can make 11 using only four 2s by using the following mathematical expression: (2 + 2) x (2 + 2) = 4 x 4 = 16. Then, subtract (2/2) to get 16 - 1 = 15. Finally, take the square root of 15 to get √15 ≈ 3.87, which is close to 4. Therefore, using four 2s, you can approximate 11 by following these steps.
How do you get 4 when using four 2s in addition subtraction division or multiplication?
(2 + 2)*2/2 = 4
How do you get 24 using four 2s?
(2*2)! * 2/2 = 4! * 1 = 24 * 1 = 24
how ,any 2s are in a deck of cards?
There are four 2s in a deck of cards, one of each suit.
Four years ago Jane was twice as old as Sam. Four years on from now Sam will be 34 of Jane's age. How old is Jane now?
Assuming 34 is 3/4:Jane is 12To solve:S+4 = 3/4(J+4)(J-4) = 2(S-4)S = 3/4(J+4)-4J = 2S-4S=3/4(2S-4+4)-4S=3/4(2S)-4S=8J=2(8)-4=12
How do you determine the equation for the perpendicular bisector of the straight line joining the points s 2s and 3s 8s?
A = (s, 2s), B = (3s, 8s) The midpoint of AB is C = [(s + 3s)/2, (2s + 8s)/2] = [4s/2, 10s/2] = (2s, 5s) Gradient of AB = (8s - 2s)/(3s - s) = 6s/2s = 3 Gradient of perpendicular to AB = -1/(slope AB) = -1/3 Now, line through C = (2s, 5s) with gradient -1/3 is y - 5s = -1/3*(x - 2s) = 1/3*(2s - x) or 3y - 15s = 2s - x or x + 3y = 17s
