5)
= - i - 2 - 3i
= - 4i - 2
= - 2 (2i + 1)
7)
= - 4 [(2 -2i - i (8 - 4i)]
= - 4 (2 - 2i - 8i + 4i^2)
= - 4 (4i^2 - 10i + 2)
= (- 4) (2) (2i^2 - 5i + 1)
= - 8 (2i^2 - 5i + 1)
9)
= p^2 - 4p - 4p + 16
= p (p - 4) - 4 (p - 4)
= (p - 4) (p - 4)
= (p - 4) ^2
11)
= p^2 - 8p - 8p + 64
= b (b - 8) - 8 (b - 8)
= (b - 8) (b - 8)
= (b - 8)^2
Answer:
The length of the sides are 9 units, 18 units and 11 units
Step-by-step explanation:
Let
x ----> one side of the triangle
y ----> the longest side of the triangle
z ----> the third side of the triangle
we know that
The perimeter of triangle is equal to

we have

so
----> equation A
-----> equation B
----> equation C
substitute equation B and equation C in equation A
solve for y


<em>Find the value of x</em>
---> 
<em>Find the value of z</em>
----> 
therefore
The length of the sides are 9 units, 18 units and 11 units
Answer:
the answer is zero cause theirs only y no x
Step-by-step explanation:
Answer:
x = 25
Step-by-step explanation:
b² + h² = x²
24² + 7² = x²
576 + 49 = x²
625 = x²
√625 = √x²
25 = x
