If she mowed 3/4 of the lawn before then after she would have to mow 1/4
The solution of 4x - 8 + 3x = 49 - 73 + 4x - 1 + 2 is equal to
<u>Solution:</u>
Given, equation is 4x – 8 + 3x = 49 – 73 + 4x – 1 + 2
We have to solve the above given equation for x.
Now, take the given equation.
4x – 8 + 3x = 49 – 73 + 4x – 1 + 2
Adding the like terms we get,
7x – 8 = - 14 + 4x + 1
7x – 4x = - 14 + 1 + 8
3x = - 14 + 9
3x = - 5
Hence, the value of x is
Hello :
<span>√(4x+13) = 2x-1......(1)
note : if ( a=b) so (a² = b²)
if : (</span>√(4x+13) )²= (2x-1)² so : 4x+13 = 4x²-4x+1
4x²-8x-12 = 0
x²-2x-3 = 0
(x+1)(x-3) = 0
x+1 = 0 or x-3=0
x= -1 or x=3
if : x= -1 : <span>√(4(-1)+13) = 2(-1)-1
</span>√9 =-3 but √9 =3
3 = -3 impossible ( -1 is not solution of equation (1)
if : x = 3 : √(4(3)+13) = 2(3)-1
5 = 5 ( right) conclusion : one solution : 3
Answer:
none of these unless one of the 45s are 46
Step-by-step explanation:
nearest dollar means no cents so $46.60 and $45.60 are out
58 is over 50 so the two 45s go away
the only option left is none of these or 46 if you accidentally put 45 instead of 46
X^4 and 2x^2
