First you use the distributive property. So, 3 times 1 and 3 times -xx = 2 times -4x and 2 times 7. This becomes 3-9x = -8x+14. Subtract 3 from both sides and add 8x to both sides and you get -x=11, so x=-11

The ages of three siblings are all consecutive

ankoles [38]

Answer:

12 year old is the youngest sibling

Step-by-step explanation:

Given: The ages of three siblings are all consecutive integers.

The sum of sibling´s age is 39.

Now, finding the age of youngest sibling.

Lets assume the age of youngest sibling be "x"

As given, The ages of three siblings are all consecutive integers.

∴ Age of 2nd sibling will be $(x+1)$

Age of 3rd sibling will be $(x+2)$

next, forming an equation for the sum of sibling´s age.

⇒ $x+(x+1)+(x+2)= 39$

Opening the parenthesis

⇒ $x+x+1+x+2= 39$

⇒ $3x+3= 39$

Subtracting both side by 3

⇒ $3x= 39-3$

⇒ $3x= 36$

Dividing both side by 3

⇒ $x= \frac{36}{3}$

∴ x= 12

Subtituting the value of x to find the age of other sibling

∴Youngest sibling age= 12 years

2nd sibling age= 13 years

3rd sibling age= 14 years

Hence, The youngest sibling is 12 years old.

Find EF if EM= x^2+25 and MF = 10x

N76 [4]

Answer:

x^2 + 10x + 25; (x + 5)^2.

Step-by-step explanation:

When we're talking about line segments, we just have to find the sum of the two parts of the line segment to find the value of the whole. In this case, we have x^2 + 25, and 10x. So, we add them together.

x^2 + 25 + 10x

= x^2 + 10x + 25

Since this can be immediately factored into (x + 5)^2, you have your answer.

Hope this helps!
