Add all then divided okay hope that helps 5
1. Maple and Oak (touch but without a right angle)
2. Maple and Birch (will never meet and are same distance from each other forever)
Answer:A
Step-by-step explanation:
-8=a(2+5)^2 + 41
-8=a x 7^2 + 41
-8=a x 7 x 7 +41
-8=49a+41
Collect like terms
-8-41=49a
-49=49a
Divide both sides by 49
-49/49=49a/49
-1=a
a=-1
Answer:
A) 2k+4
Step-by-step explanation:
To solve for terms of x, we need to. she sure that x is on its own side while every other term is on the other side.
To start, we will cross multiply. If we have a/b=c/d, then ad=bc
We can perform the same calculation here,
6/x=3/(k+2)
6(k+2)=3x
Divide both sides by 3
2(k+2)=x
x=2k+4
Answer:
Step-by-step explanation:
Given that:
sin2xcos x + cos2xsin x = -1
Recall that;
SInAcosB + cosASinB = SIn (A+B)
SIn (2x +x) = -1
Sin (3x) = -1
![x = \bigg [\dfrac{Sin ^{-1} (-1)}{3} \bigg ]](https://tex.z-dn.net/?f=x%20%3D%20%5Cbigg%20%5B%5Cdfrac%7BSin%20%5E%7B-1%7D%20%28-1%29%7D%7B3%7D%20%20%5Cbigg%20%5D)
