I believe 6:12 is equivalent to 3:6
The scale factor of the two triangles is 3.
<h3>What is Scale Factor?</h3>
Scale factor is a number by which the size of any geometrical figure or shape can be changed with respect to its original size.
Here, Two triangles have angles with the same degrees or Similar triangles.
Scale factor = Base of bigger triangle / base of smaller triangle
= 21 / 7
= 3
Thus, the scale factor of the two triangles is 3.

Answer:
x= 2
Step-by-step explanation:
so you add the values given in the brackets and leave X as it is (do this on both sides of the equation.
1. (x + 5)(x+4)= (x+12)(x+1)
2. multiply the parenthesis on both sides or one at a time
so, 
+5x+4x+20 = +12+1x+12
3. cancel like terms which we have so remove that.
5x+4x+20=12+1x+12
4. collect like terms.
9x + 20 = 13x + 12
5. move like terms.
9x-13x=12-20 = -4 = -8
6. x= 
divide both sides by 4 or basically simplify 4 divided by 8
which leaves u with
x= 2
hope this helps x, let me know if u have any questions. photomath is an app that helps too.
3.7 and 4.7 because you are just adding 0.5 each time.
So if the delievery man weighs 160 pounds and the books is 40 pounds. and the capacity he can carry is 950 then we have to figure out how many books a 160 can carry.
Division: 160/40=4
950/4=237.5
i tried to answer it. unless i try one more strategy.
Multiply: 160*40=6400
Divison: 6400/950= <span>6.73684210526
</span>try and round that huge number and figure it out. because i tried. im sorry. i hope you passed.
