The equivalent expression of (\sqrt x - 2)(\sqrt x + 9) is x + 7\sqrt x - 18

<h3>How to determine the equivalent equation?</h3>

The expression is given as:

(\sqrt x - 2)(\sqrt x + 9)

Expand the expression

x - 2\sqrt x + 9\sqrt x - 18

Evaluate the like terms

x + 7\sqrt x - 18

Hence, the equivalent expression of (\sqrt x - 2)(\sqrt x + 9) is x + 7\sqrt x - 18

Use I = PRT to solve.
Mice21 [21]

Answer:

Time T = 15 year

Step-by-step explanation:

Given:

Interest I = $270,000

Principal P = $150,000

Rate R = 12% = 0.12

Find:

Time T

Computation:

I = PRT

270,000 = (150,000)(0.12)(T)

270,000 = (18,000)(T)

Time T = 15 year

Find missing number from letter n ! Please
Ira Lisetskai [31]

Answer:

1. n= 20 /13

2. n=10

3. n=35

4. n=9

That's all I could do, I got tired of typing lol

Step-by-step explanation:

1.  4/n=13/5 we cross multiply, (4)*(5)=13*n, 20=13n Flip the equation.  13n=20, divide 13 on both sides, 13n/13=20/13, n= 20 /13

2. 9/6= 15/n, we cross multiply 9*n=(15)*(6), 9n=90, Divide both sides by 9. 9n/9=90/9 n=10

3. 28/4=n/5 Cross-multiply, (28)*(5)=n*(4), 140=4n Flip the equation.4n=140 Divide both sides by 4. 4n/4=140/4 n=35

4. n/6=6/4 we cross multiply,n*(4)=(6)*(6), 4n=36, Divide both sides by 4 4n/4=36/4.  n=9
