Answer:

x = 1.125 AKA x = 1 1/8 AKA x = 9/8

Step-by-step explanation:

CB to ED = 1 : 9

Scale Factor = 1/9

$\frac{1}{9} = \frac{x}{x+9}$ -> cross multiply

9x = x + 9

-x -x

8x = 9

$\frac{8x}{8} =\frac{9}{8}$

x = 9/8

Hello,

$(x+7)(x+2)=50\\\Rightarrow\ x^2+9x+14=50\\\Rightarrow\ x^2+9x-36=0\\\Rightarrow\ x^2+12x-3x-36=0\\\Rightarrow\ x(x+12)-3(x+12)=0\\\Rightarrow\ (x+12)(x-3)=0\\\Rightarrow\ x=-12\ or\ x=3\\If \ x=-12\ then\ x+7$

geniusboy [140]

Answer:

Integers and polynomials are both closed under addition, subtraction, and multiplication; however, operations on polynomials can sometimes be open while operations on integers produce irrational results .

Step-by-step explanation:

Closed means that addition, subtraction, and multiplication of integers gives as result a new integer; and addition, subtraction, and multiplication of polynomials gives as result a new polynomial.

Operations on polynomials can sometimes be open, like in division.

Operations on integers can produce irrational results , for example, dividing 11 by 9.
