Answer:

x=4

Step-by-step explanation:

we know the ratio of left to right is 2:1 because 6:3=2:1

the horizontal lines are parallel, so the other set of numbers follows the same proportions

$x^{2} +2x+11=2(x+13.5)\\x^{2} +2x+11=2x+27\\x^{2} +2x-2x=27-11\\x^{2} =16\\x=\sqrt{16} \\x=4$

Answer:

x = 6•3 == 18

18² = 324

324 + 2 + 11 = 337

Step-by-step explanation:

Order of Operations; PEMDAS

Parentheses

Exponents

Multiplication & Division (Left to Right) (ex: 10x2÷5) You would do whatever comes left for Multiplication or Division.

Addition & Subtraction (Left to Right) (ex: 10-2+5) You would do whatever comes left for Addition & Subtraction.

You have a 32-foot fence around a square garden. You paint 1/3 of one side of the fence. What fraction of the fence did you pain

dmitriy555 [2]

The answer is 1/12.

The perimeter of a square garden with side s is:
P = 4s

s = 1/4P

Since it is painted 1/3 of 1/4 of the fence, the fraction of the painted fence is:
1/3 * 1/4 = 1/12

Solve the following 2 equation. I will Make Brainliest

Levart [38]

Answer:

d. $x = 10$

e. $x=\sqrt[3]{\dfrac{15}{4}}$

Step-by-step explanation:

I've typed up my workings in MS Word and attached them (as it's very difficult to type this in the Brainly equation editor).

I've used the product, quotient and power log laws.

Product: $log_a(x)+log_a(y)=log_a(xy)$

Quotient: $log_a(x)-log_a(y)=log_a(\dfrac{x}{y})$

Power: $p\log_a(x)=log_a(x^p)$
