Answer:</h2><h2>Yes, the simplified form of 2 square root of 3 − 2 square root of 3 is rational.</h2>
Step-by-step explanation:
The given expression is 
After performing the subtraction operation, the result is 0 as the terms are equal and opposite in sign, they cancel each other.
Rational numbers are those which can be expressed in the form of fractions, decimals, e.t.c
Since 0 can be expressed as a fraction, it is a rational number.
For eg: 
= 0,
Hence the result of the given expression is a rational number.
Answer:
5.5
Step-by-step explanation:
5.5/10 = 8.5/(y+10)
if you solve it, it'll look like
y = 60/11
which is approximately 5.5

(f-g)(x) = x²+6x - (7-x)
(f-g)(x) = x² + 6x - 7 + x
(f-g)(x) = x² + 7x - 7
(f-g)(9) = 9² + 7*9 - 7
(f-g)(9) = 81 + 63 - 7
(f-g)(9) = 137
The approximate area of the triangular base of James’ tank is 3025 in²
To find the approximate area of the triangular base of James' tank, we need to know what scale is.
<h3>What is scale?</h3>
A scale is the ratio of two dimension. It is given by scale = New dimension/old dimension
Given that the dimensions of James’ tank are each exactly 2 3/4 times the dimensions of Julian’s tank.
The scale of the area of James' tank to the area of triangular base of Julian's tank is S = (2³/₄)²
= (11/4)²
= 121/16
Let
- A = area of triangular base of James' tank,
- A' = area of triangular base of Julian's tank = 400 in²
So, scale, S = A/A'
<h3>
The approximate area of the triangular base of James’ tank</h3>
So, making A subject of the formula, we have
A = SA'
A = 121/16 × 400 in²
A = 121 × 25 in²
A = 3025 in²
So, the approximate area of the triangular base of James’ tank is 3025 in²
