svp [43]

Answer:

$Xs=30cm$ and $As=900 cm^{2}$

Step-by-step explanation:

At=As+Ar; A=b.h and $At=4500 cm^{2}$ , then: At=(x+120)x so

(x+120)x=4500, $x^{2} +120x-4500=0$ Applying cuadratic equation formula: $\frac{120+-\sqrt{120^{2} -4.1.-4500} }{2} =-\frac{120+-\sqrt{14400+18000} }{2}= x1=30 and x2=-150, finally Xs=30cm, and As=900cm^{2}$

Express the answer in standard form.

Natali [406]

Answer:

$-2x^{2} +8x-10$

Step-by-step explanation:

Standard form is basically where the degrees of the terms are in descending order.

First, let's distribute the negative sign to the terms in the second parentheses:

$-(3x^{2} -5x+3) = -3x^{2} +5x-3$

Now, we can just combine like terms with the terms from the first parentheses:

$x^{2} +3x - 7 - 3x^{2} +5x-3 = -2x^{2} +8x-10$

So, our answer is: $-2x^{2} +8x-10$
