try asking the teacher if you could get some help Step-by-step explanation:
Answer:
and 
Step-by-step explanation:
(a)
A =
× 4
× 
= 2
× 
=
×
← rationalise the denominator
=
units²
(b)
Using Pythagoras' identity in the right triangle
let hypotenuse be h , then
h² = (4
)² + (
)²
= 32 + 
=
+ 
=
( take the square root of both sides )
h =
=
×
← rationalise the denominator
h = 
Lets find that number:
3 < x < 4
that can easily be thought as 3.5
<span>3 < 3.5 < 4
</span>now lets change the decimal to a mix number:
3.5 = 3 + 0.5
= 3 + 5/10
= 3 + 1/2
= 3 1/2
Answer:
y ≥ 28
Step-by-step explanation:
Isolate the variable. Treat the inequality sign as a equal sign, what you do to one side, you do to the other. Add 6 to both sides:
y - 6 (+6) ≥ 22 (+6)
y ≥ 22 + 6
y ≥ 28
y ≥ 28 is your answer.
