Let the marks of Devi be x and Ali be y.

So, the equations:

2y = x <em>and</em> y + 16 = x

So,

2y = y + 16. [ because we know equals are equal to equals]

=> 2y - y = 16

=> y = 16

Check

Ali's marks are half of Devi's marks.

Devi's marks are 16 more than alis.

So, Devi's marks will be 16×2 = 32 and 32 is 16 greater than 16 (16+16=32).

Factor this polynomial expression. X^2 + 8x + 16

andrezito [222]

Answer:

D. (x + 4)(x + 4)

Step-by-step explanation:

The poynomial x^2 + 8x + 16 is a perfect trinomial.

Perfect trinomials are when the square root of the first term, multiplied by the square root of the third term, multiplied by 2, is equal to the middle term.

In trinomial ax² + bx + c, it is perfect when:

(2) (√(ax²)) (√c) = bx

In x² + 8x + 16,

2(√x²)(√16) = 8x

The formula for a perfect trinomial is:

ax² ± bx + c = (√(ax²) ± √c)(√(ax²) ± √c) = (√(ax²) ± √c)²

Open up two brackets. Square the first and last term, and they are either added or subtracted based on the sign before the middle term.

In x² + 8x + 16,

(√x² + √16)² = (x + 4)² = (x + 4)(x + 4)
