The answer is 15 - 5 x
Multiply 5 by 3 ( 15 )
Multiply 5 by -x ( -5x )

A = lw
A = (5 × 10^3)(6 × 10^2)
= 5000 × 600
= 300000
= 3 × 10^6 m^2
Answer: second option y = 2(x + 7/2)^2 + 1/2
Explanation:
1) given:
y = (x + 3)^2 + (x + 4)^2
2) expand the binomials:
y = x^2 + 6x + 9 + x^2 + 8x + 16
3) add like terms:
y = 2x^2 + 14x + 25
4) take common factor 2 of the first two terms:
y = 2 (x^2 + 7x) + 25
5) complete squares for x^2 + 7x
x^2 + 7x = [x +(7/2)x ]^2 - 49/4
6) substitue x^2 + 7x = (x + 7/2)^2 - 49/4 in the equation for y:
y = 2 [ (x + 7/2)^2 - 49/4] + 25
7) take -49/4 out of the square brackets.
y = 2 (x + 7/2)^2 - 49/2 + 25
8) add like terms:
y = 2(x + 7/2)^2 + 1/2
And that is the vertex for of the given expression.
X=1 1/3 is that helpful because I don’t know if it’s right
Based on the amount that Nader can pay per month, and the interest rate as well as the period, the amount he could spend if the rate was annual is $8,385.33.
<h3 /><h3>How much could Nader spend on the car?</h3>
If Nader can pay $280 per month, the amount he can pay per year i:
= 280 x 12
= $3,360
The amount that he can spend on the car is the present value of these yearly payments:
= 3,360 x (1 - (1 + 9.8%)⁻³) / 9.8%
= 3,360 x 2.49563439768461
= $8,385.33
