Answer:

30 years

Step-by-step explanation:

let the age of Ezekiel be x years

Given

Lily is 14 years older than her little brother Ezekiel

Age of Lily = x + 14 years

Next condition

after 8 years\

age of Ezekiel = x+8

age of Lily = x + 8 +14 = x + 22 years

Given

. In 8 years, Lily will be twice as old as Ezekiel will be then.

Thus,

x + 22 = 2(x+8)

=> x + 22 = 2x + 16

=> 22-16 = 2x -x

=> x = 6

Thus, age of  Ezekiel = 8 years

age of lily = 8+14 = 22 years

sum of their age = 22 + 8 = 30 years      answer.

Prove that the value of the expression: 731^2−631^2 is divisible by 100
Ivanshal [37]

Answer:

Step-by-step explanation:

731² - 631² is the difference of squares.

731² - 631² = (731+631)(731-631) = 1362×100

therefore, 731² - 631² is divisible by 100

Find the area and perimeter of the square 6 meters
Mkey [24]
<h2>AREA</h2>

The formula for finding area of a square is:

length \times width

In a square, all the sides are the same. Each side is 6 meters long. Plug in 6 to the formula.

length \times width \rightarrow 6 \times 6

Multiply:

6 \times 6 = 36

The area of the square is 36 m²

<h2>PERIMETER</h2>

Perimeter is the distance around a shape. To find perimeter, you have to add all all the side lengths. The formula for finding perimeter is:

2(l) \times 2(w)

Remember that squares have 4 sides, and all length(s) and width(s) measure the same. The length and width measure the same. Plug in the numbers into the formula:

2(l) + 2(w) \rightarrow 2(6) + 2(6)

Simplify:

2(6) + 2(6) = 12 + 12

Add:

12 + 12 = 24

The perimeter of the square is 24 m

Please answer this, thanks.

First, put it into point-slope form. 

Find the slope:

m=(y2-y1)/(x2-x1)
m=(-6-(-2)/(2-1)
m=(-6+2)/1
m=-4/1
m=-4

Now, put it into point-slope:

y-y1=m(x-x1)

y-2=-4(x-(-6)
y-2=-4(x+6)
y-2=-4x-24

Slope intercept form: y= mx+b

Add 2 to the other side.

y=-4x-22 <== the answer

I hope this helps!
