For all values of x,<br> x² + 6x - 2 = (x+p)² + q<br> Find the value of p and the value of q.
Vlad [161]

Step-by-step explanation:

{p}^{2}  + q =   - 2

p = 3

Maria invested $450 in a savings account and earned $126 in interest at the end of 7 years.
Brut [27]
The interest rate is B. 4%

Given:
Principal = 450
Interest = 126
term = 7 
rate = ?

Simple Interest is computed by multiplying the Principal, rate, and term.

Interest = P × r × t

126 = 450 × r × 7
126 = 3150r
r = 126/3150
r = 0.04 x 100% = 4%

To check:

I = 450 
× 0.04 x 7
I = 18 × 7
I = 126
