Answer:
AC = 7.5 cm
Step-by-step explanation:
Given that the triangles are similar then the ratios of corresponding sides are equal, that is
=
, substitute values
=
, that is
=
( cross- multiply )
7AC = 52.5 ( divide both sides by 7 )
AC = 7.5 cm
Answer:
c = 80:)
Step-by-step explanation:
Answer:
-15a^2+20ab
Step-by-step explanation:
Given data
We are given the expression
(-3a + 4b) to be multiplied by 5a
hence we have
(-3a + 4b)*5a
open bracket
-15a^2+20ab
Hence the answer is
-15a^2+20ab
I believe the answer is 8,538.?1
The only place I don't know is the tenths place bc idk what it means by the digit in the tenths place is the same value in every place. But the other numbers should be correct

<h3>What are Complex numbers?</h3>
A complex number is the sum of a real number and an imaginary number. A complex number is of the form a + ib and is usually represented by z. Here both a and b are real numbers. The value 'a' is called the real part which is denoted by Re(z), and 'b' is called the imaginary part Im(z).
Since we have given :
and 
The difference of z1 - z2 would be:
So,
