Answer:
n = 3
Step-by-step explanation:
2n+5-6 = 5 ( add 6 on both sides)
2n+5=11 (then subtract 5 on both sides)
2n=6 (Then divide by 2 on both sides)
<em>n = 3</em>
Answer:
a) Эx ∈ R ⊇ x³ = 2
b) ∀x ∈ R, x² ≥ 0
c) Эx ∈ R ⊇ x³ = x
d) ∀x ∈ R, x ≤ x²
Step-by-step explanation:
Given the data in the question;
let us first go through some symbols and their possible meanings;
Э ⇒ there exists
∀ ⇒ for all
∈ ⇒ belongs to or set membership or element of the set
⊇ ⇒ such that
now;
a) There is a number whose cube is equal to 2
let x represent the number; so
Эx ∈ R ⊇ x³ = 2
b) The square of every number is at least 0
x² ≥ 0, ∀x ∈ R
∀x ∈ R, x² ≥ 0
c) There is a number that is equal to its square
Эx ∈ R ⊇ x³ = x
d) Every number is less than or equal to its square.
x ≤ x², ∀x ∈ R
∀x ∈ R, x ≤ x²
Answer rude leave me alone i can type whatever i want
Answer:
x=42
Step-by-step explanation:
so they u the exterior angle is 132
line makes 180 degree
180-132 =48
now they tell u a right angle
that is 90
triangles interior angles add up to 180
180-90-48=
42
