Answer:
available is 111.5cm tall and Olivia is 88.5cm
Step-by-step explanation:
ok so Olivia is half the height of Luca which means the height of Luca divided by 2
177÷2=88.5
so Olivia is 88.5cm tall
we know that Available is 23cm taller than Olivia which means
the height Available= the height of Olivia+ 23cm
=88.5+23
=111.5
so Available is 111.5cm tall
Definition 1: Perfect squares are numbers or expressions that are the product of a
number or expression multiplied to itself (7 times 7 is 49, so 49 is a
perfect square).
Definition 2: <span>Binomials are algrebraic expressions containing only two terms.</span><span />
<span>
</span><span>
Definition 3: Trinomials are algebraic expressions that contain three terms. </span><span />
Perfect square trinomials are algebraic expressions with three terms that are created by multiplying a binomial to itself. There are two formulas for perfect square trinomials:

.
From these formulas you can see that:
A. <span>"Neither of the perfect squares can have a minus sign" is true statement;
</span>
B. "<span>The first and third terms must be perfect squares" is true statement;
</span>
C. "<span>If the perfect square terms are

and

then the other term must be

" is false statement;
</span>
D. "<span>None of the above is a property of a perfect square trinomial" is consequently false statement.

15=-4+z/3
+4 +15 = +4 -4 +z/3
cancels the 4 on the right side
19 = z/3
3 x 19 = z/3 x 3
cancels 3 on the right side
I think the answer is z = 57
Answer:
<h2>
4.16%</h2>
Step-by-step explanation:
decrease 7%
100 - 7% = 93
increase 12%
93 + 12% = 104.16
104.16 - 100 = 4.16%
Angles on a straight line add up to 180 so take 91 away from 180 to give you 89 i guess ^^; i hope that helps somewhat
