Answer:
A histogram
Step-by-step explanation:
This type of graph is used with quantitative data. Ranges of values, called classes, are listed at the bottom, and the classes with greater frequencies have taller bars.
Yes the triangles are similar.
There is a common rate of dilation from the second triangle to the first. Each side can be multiplied/divided by three to find the other length.
I hope is helps.
Answer:
ok well whats the question
Step-by-step explanation:
Factor by grouping.
0 = (x^3 +4x^2) +(9x +36) = x^2(x+4) +9(x+4) = (x^2+9)(x+4)
The first factor is the difference of squares (in complex numbers), so the form for factoring that can be used:
a^2 - b^2 = (a -b)(a +b)
Here, a=x, b=3i.
Then the factorization in complex numbers is
0 = (x -3i)(x +3i)(x +4)
Solutions are the values of x that make these factors be zero.
x = -4, -3i, 3i
-2x - 2 = -6(1 + 4x) ...distribute thru the parenthesis
-2x - 2 = -6 - 24x ....add 24x to both sides
-2x + 24x - 2 = -6 - 24x + 24x...simplify
22x - 2 = -6 ...add 2 to both sides
22x - 2 + 2 = -6 + 2 ...simplify
22x = -4 ...divide both sides by 22
x = -4/22 which reduces to - 2/11 <==
