a + 3a - 2 + 3a. Add the a + 3a + 3a = 7a. You can't combine the -2 & 7a so the solution is: 7a - 2.
37
7a + 4 = 5a + 7 7a = 5a + 3 2a = 3 a = 3/2
To factorize the expression 7a^2 - 8ab, you need to find the greatest common factor of the two terms. In this case, the common factor is a. So, you can factor out an 'a' to get a(7a - 8b) as the factored form of the expression. This means that 7a^2 - 8ab can be simplified as a multiplied by the quantity (7a - 8b).
7a=2(-10)........................................answer is 20/7
It is: (7*4)-(2*2)+1 = 25
(a^2+7a-8)/(a^2+6a-7) (original equation) (a+8)(a-1)/(a+7)(a-1) (simplify top and bottom) (a+8)/(a+7) <--answer
(a2 + 5a + 6)/(a - 2) = (a + 2)*(a 3)/(a - 2) which cannot be simplified further. It can, however be written as (a2 - 2a + 7a - 14 + 20)/(a - 2) which is (a + 7) + 20/(a - 2)
The discriminant is b^2-4ac. So, b=7, a=2, and c=3. 7^2=49-4(2)(3)=49-24=25. So the discriminant is 25.
a2-36=0 2a=36 a=36/2 a=18 Hence, the required value is a is 18.
Pythagorean Theorem: a2+b2=c2. So if the length is 4cm and the width is 3cm: a2+b2=c2 (3)2+(4)2=(5)2 9+16=25 25=25 Therefore, the diagonal would be 5cm.
It is not clear exactly what you would like to do, but try something like this in your worksheet code module: Private Sub Worksheet_Change(ByVal Target As Range) If Target.Address <> "$A$2" Then Exit Sub If Range("A2").Value > 0 Then Range("A2").Value = Range("A2").Value + Range("B2").Value Else Range("A2").ClearContents End If End Sub The value of A2 will update with =A2+B2 every time you change the value in A2.
sqrt(a2 + a2) = sqrt(2a2) = sqrt(2)*sqrt(a2) = sqrt(2)*asqrt(a2 + a2) = sqrt(2a2) = sqrt(2)*sqrt(a2) = sqrt(2)*asqrt(a2 + a2) = sqrt(2a2) = sqrt(2)*sqrt(a2) = sqrt(2)*asqrt(a2 + a2) = sqrt(2a2) = sqrt(2)*sqrt(a2) = sqrt(2)*a
a + 3a - 2 + 3a. Add the a + 3a + 3a = 7a. You can't combine the -2 & 7a so the solution is: 7a - 2.
The square root function is SQRT, like this:=SQRT(value)To square a number, either multiply it by itself, using the POWER function or the power operator. If you had a value in cell A2, all of the following would do the same thing:=A2*A2=POWER(A2,2)=A2^2
The forward slash (/) is the division symbol in Excel. =A1/A2 divides the value of cell A1 by the value of cell A2.
2 a2 is a monomial, not a binomial but 2 + a2 is a binomial, so is 2 - a2 .
