9.which of the following ordered pairs is a solution of the given system of linear equations answer choices and question are in picture you so much!

Option C. The solution is the point (1,8)

Step-by-step explanation:

we have

-----> equation A

----> equation B

Solve the system by elimination

Multiply the equation A by -1 both sides

-----> equation C

Adds equation C and equation B

Find the value of x

----> ---->

therefore

The solution is the point (1,8)

the answer is c

Step-by-step explanation:

all steps are pictured

answer: i guess 5 units?

step-by-step explanation:

area of rectangle a is 2 times that of rectangle b that means 2x+x =   36cm^2

3x = 36cm ^2

x = 36/3

x= 12cm^2

and 2x = 24cm^2

now side of square = are divided by sides = 36/4 = 6cm

that means length of rectangle a and b is 6cm too

now for rectangle a,

l*b = area

= 6*y=24

y=24/6 = 4

therefore dimensions of rectangle a are- length = 6cm, breadth = 4cm

and for rectangle b, length = 6cm and breadth = 6-4 = 2cm.

hope this .
