It is: 7 times 7 equals 49
If that's 16x2 + 72x + 81, that factors to (4x + 9)(4x + 9) or (4x + 9)2
49 x 7
Yes, and this is how. 16 x 2 - 9 16x2=32, 32 - 9 =23, so 23 is your answer! Good Question!
49 does not go into 189 evenly. 189 divided by 49 equals 3 with a remainder of 42.
16x2 - 56x + 49 = (4x - 7)2
(4x - 7)(4x + 7)
4x times 4x equals 16x2.
Equals means=ok
(4x + 7)(16x2 - 28x + 49)
y = -16x2 + 342At the x-intercepts, y=0-16x2 + 342 = 016x2 = 342x2 = 342/16 = 21.375x = plus and minus sqrt(21.375) = approx. plus and minus 4.6233 (rounded)
49 - 30 equals = 19
sqrt(10x)*sqrt(8x) = sqrt(80x2) = sqrt(16x2*5) = sqrt(16x2)*sqrt(5) = 4x*sqrt(5)
If you can't factor it easily, use the quadratic formula.
16x2 + 8x + 1 = 0 : This factorises to (4x + 1)(4x + 1) = 0 When 4x + 1 = 0 then 4x = -1 : x = -1/4.
The number that equals the 2nd power of 49 is the square root of 49. In this case, the square root of 49 is 7, because 7 multiplied by itself (7^2) equals 49. Therefore, the number that equals the 2nd power of 49 is 7.
the answer is 98
