If √x + 8 = 7, then √x = -1, so x does not exist, because √ only refers to positive roots.
If √(x + 8) = 7, then x + 8 = 49 and x + 41.

2 plus 3 equals 8 3 plus 7 equals 27 4 plus 5 equals 32 5 plus 8 equals 60 6 plus 7 equals 72 7 plus 8 equals what?
89
What is the length of the line y equals 8 -x that meets the curve of y equals x squared plus 4x plus 2 at two distinctive points?
7*sqrt(2) = 9.899 to 3 dp
What are the solutions of 5x2 plus 8x equals 7?
5x2 + 8x = 7 5x2 + 8x - 7 = 0 This cannot be factorised so the solutions need to be determined using the quadratic formula The solutions are {-8 ± sqrt[82 - 4*5*(-7)]}/(2*5) = {-8 ± sqrt[64 + 140]}/10 = {-8 ± sqrt[204]}/10 = -2.22829 and 0.62829 (to 5 dp)
If 2 plus 3 equals 10 and 7 plus 2 equals 63 and 6 plus 5 equals 66 and 8 plus 4 equals 96 and 8 plus 4 equals 96 then 9 plus 7 equals?
144 9+7 = 16 and 9*16 = 144
What is the solution for x if sqrt parentheses 4x plus 7 endparentheses minus 4 equals sqrt parentheses 4x minus 1 endparentheses?
sqrt(4x+7) -4 = sqrt(4x-1) squared : (sqrt(4x+7) -4)2 = 4x-1 (4x+7) - 2x4xsqrt(4x+7) +16 = 4x-1 -8xsqrt(4x+7) = -24 sqrt(4x+7) = -24/-8 = 3 squared : 4x+7 = 32 = 9 4x = 9-7 = 2 then x=1/2
2 plus 3 equals 8 3 plus 7 equals 27 4 plus 5 equals 32 5 plus 8 equals 60 6 plus 7 equals 72 7 plus 8 equals what?
89
6 plus 7 plus 8 equals 6 plus 8 plus 7 what property is that?
6 plus 7 plus 8 equals 6 plus 8 plus 7, what property is that?That is the associative property.
8 plus 7 plus 5 equals plus 8 equals?
it is 28
What is the length of the line y equals 8 -x that meets the curve of y equals x squared plus 4x plus 2 at two distinctive points?
7*sqrt(2) = 9.899 to 3 dp
How do you divide 28 by the square root of 8?
28/sqrt(8) multiply top and bottom by sqrt(8) = 28*sqrt(8)/[sqrt(8)*sqrt(8)] = 28*sqrt(8)/8 = 7*sqrt(8)/2 But sqrt(8) = sqrt(4*2)= sqrt(4)*sqrt(2) = ±2*sqrt(2) then 7*sqrt(8)/2 = ±7*2*sqrt(2)/2 = ±7*sqrt(2)
What are the solutions of 5x2 plus 8x equals 7?
5x2 + 8x = 7 5x2 + 8x - 7 = 0 This cannot be factorised so the solutions need to be determined using the quadratic formula The solutions are {-8 ± sqrt[82 - 4*5*(-7)]}/(2*5) = {-8 ± sqrt[64 + 140]}/10 = {-8 ± sqrt[204]}/10 = -2.22829 and 0.62829 (to 5 dp)
If 6 plus 7 equals 78 7 plus 2 equal 63 and 8 plus 4 equals 96 then 9 plus 7 equals?
144
If 2 plus 3 equals 10 and 7 plus 2 equals 63 and 6 plus 5 equals 66 and 8 plus 4 equals 96 and 8 plus 4 equals 96 then 9 plus 7 equals?
144 9+7 = 16 and 9*16 = 144
2 plus 3 equals 10 and 7 plus 2 equals 63 and 6 plus 5 equals 66 and 8 plus 4 equals 96 Then 9 plus 7 equals?
If I am correct, 9 plus 7 equals 112.
What is the solution for x if sqrt parentheses 4x plus 7 endparentheses minus 4 equals sqrt parentheses 4x minus 1 endparentheses?
sqrt(4x+7) -4 = sqrt(4x-1) squared : (sqrt(4x+7) -4)2 = 4x-1 (4x+7) - 2x4xsqrt(4x+7) +16 = 4x-1 -8xsqrt(4x+7) = -24 sqrt(4x+7) = -24/-8 = 3 squared : 4x+7 = 32 = 9 4x = 9-7 = 2 then x=1/2
What does -15 plus 7 equals?
-8
If 2 plus 3 equals 10 7 plus 2 equals 65 6 plus 5 equals 66 8 plus 4 equals 96 then what 9 plus 7 equals?
