Answer:

Option A : 15x² + 62x + 63 is the correct answer.

Step-by-step explanation:

Given measurements of the figure are:

5x + 9 and 3x + 7

We have to find the area. We can find the area by multiplying the two expressions.

Area = (5x+9) * (3x+7)

Area = 5x (3x+7) +9(3x+7)

Area = 15x² + 35x + 27x + 63

Area = 15x² + 62x + 63

Hence,

Option A : 15x² + 62x + 63 is the correct answer.

What are the solutions to x^2-5x+3=0?

Viktor [21]

Answer:

Step-by-step explanation:

You need to use the quadratic equation

x = $\frac{-b +/- \sqrt{b^2 - 4ac} }{2a}$

Givens

a = 1
b = - 5
c = 3

x = $\frac{5 +/- \sqrt{5^2 - 4a*1*3} }{2} \\$

x =( 5 +/- sqrt(25 - 12) ) / 2

x = (5 +/- sqrt(13) )/2

x = (5 + sqrt(13) / 2

x = 4.303 rounded

x = (5 - sqrt(13) ) /2

x = .6972
