Step-by-step explanation: 22=4 IS LIKE EASY BUT IF YOU FORGOT THEN THATS FINE
Answer:
k = 11
Step-by-step explanation:
Given the points are collinear then the slopes between consecutive points are equal.
Using the slope formula
m = 
with (x₁, y₁ ) = (5, 1) and (x₂, y₂ ) = (1, - 1)
m =
=
= 
Repeat with another 2 points and equate to 
with (x₁, y₁ ) = (1, - 1) and (x₂, y₂ ) = (k, 4)
m =
, then
=
( cross- multiply )
k - 1 = 10 ( add 1 to both sides )
k = 11
Usually you use addition to find a sum.
Answer:
<h2> b = 2(3t + 4)(2t + 9)</h2>
Step-by-step explanation:
![12t^2+70t+72=2(6t^2+35t+36)=2(6t^2+27t+8t+36)\\\\=2[3t(2t+9)+4(2t+9)]=2(2t+9)(3t+4)](https://tex.z-dn.net/?f=12t%5E2%2B70t%2B72%3D2%286t%5E2%2B35t%2B36%29%3D2%286t%5E2%2B27t%2B8t%2B36%29%5C%5C%5C%5C%3D2%5B3t%282t%2B9%29%2B4%282t%2B9%29%5D%3D2%282t%2B9%29%283t%2B4%29)
