Step-by-step explanation:

24a³ + 37a² – 5a =

a ( 24a²+ 37a -5) =

a( 24a² +40a -3a -5) =

a [8a(3a+5) -1(3a+5) ]=

crimeas [40]
Grouping is when you have to terms that are the same inside the parenthesis and a different or same number outside the parenthesis and then the one inside the parenthesis u are going to group them not combined them and write them once and the numbers inside the parenthesis group them together by adding them and put parenthesis between them

Ex
5(4x+1)10(4x+1)
(5+10)(4x+1)

How would i find h please help!!

Answer:

35

Step-by-step explanation:

So the triangle who posses the angle with measurement k=35 is an isosceles.  I know this because there are two congruent legs.  Those 2 congruent legs tell us the angles opposite of them are all congruent.

So we know one equation to solve is:

x+x+35=180 where x is the base angle in the left triangle picture.

Combine like terms:

2x+35=180

Subtract 35 on both sides:

2x=180-35

Simplify:

2x=145

Divide both sides by 2:

x=72.5

So one of the base angles of the left isosceles triangle is vertical with with another angle in the right.  This triangle on the right is also isosceles.

So we know that 72.5+72.5+h=180.

Combine like terms:

145+h=180

Subtract 145 on both sides:

h=180-145

Simplify:

h=35
