Answer:
x∈{-7√2, 7√2}
Step-by-step explanation:

Answer:
let W and R represent white toothpaste and red toothpaste represently
n(W)=143
n(R)=135
n(WnR)=70
n( WuR)=?
Now,
n(WuR)=n(W)+n(R)_n(WnR)
=143+135_70
=208
that's all don't forget to write therefore.
A full circle in radians is 2π, and in degrees it's 360°. I want to convert the 72° to radians:
72° in radians = 72/360 * 2π = 2/5π
The circumference of a full circle is the number of radians times the radius. (ie., 2πr), so the JK part of the circle is:
5* 2/5π simplifies to 2π
Just remember that
1meter=100 cm
81.66m=81.66*100=8166 cm
parallelogram , opposite sides are equal
so
PR = QS
and
PQ = RS
4x - 1 = 3x + 7
x = 8
PQ = 4(8) - 1 = 32 -1 = 31
Given P = 74 cm
74 - 2(31) = 12
PR = QS = 12/2 = 6
Answer
QS = 6 cm
