Answer:

Part a)

Steve's expression is 2(2x+5)^{2}-7

For x=3, the expression is equal to 235

Part b)

Jasmine's expression is

(3x^{2})+(25x)

For x=2, the expression is equal to 62

Step-by-step explanation:

Part a)

Let

n-----> the first term

The expression is

(n-7)

n=2(2x+5)^{2}

substitute

Steve's expression is

2(2x+5)^{2}-7

Evaluate for x=3

2(2(3)+5)^{2}-7=242-7=235

Part b)

Let

n-----> the first term

Jasmine's expression is

(3x^{2})+(25x)

Evaluate for x=2

(3(2)^{2})+(25(2))=12+50=62
