Answer:
triangle
Step-by-step explanation:
it has 3 sides, not four
a^2 - b^2 = (a + b)(a - b)
In this case
49x^4y^2 - 4z^2
= (7x^2y)^2 - (2z)^2
= (7x^2y + 2z)(7x^2y - 2z)
Factors are (7x^2y + 2z) and (7x^2y - 2z)
Answer:
D) 7x^2y + 2z
Answer:
25
Step-by-step explanation:
(6^2+4)−15
(36+4)−15
40−15
25
The place value pattern is a system of patterns of tens in which every
place value is ten times the value on its right. The place value pattern
system is used to <span>write
numbers that are 10 times as much as or 1/10 of any given number.
The place values in the pattern are: ones, tens (10*ones), hundreds (10*tens), thousands (10*hundreds),...
So, 50 = 5 tens
5000= 5 thousands, 0 hundreds, 0 tens, 0 ones
So, 5000 > 50</span>
Given a slope 
, the slope 
of a line perpendicular to 
is the opposite of the inverse of
In other words:
So, the slope of CD is -5/2.
