The expression which represents the perimeter, in centimeters, of the rectangle is; (18d +10f) centimetres.
<h3>Perimeter of a rectangle</h3>
Since the perimeter of a rectangle is given by the formula;
In essence, Perimeter, P = 2(2d – 3f) + 2(7d + 8f)
Ultimately, the perimeter of the rectangle is; (18d +10f) centimetres.

Answer:
Real part = 3 & imaginary part = 1
2) 4 + 7i - 8 = 4 -8 + 7i
= -4 + 7i
Real part = -4 & imaginary part = 7
Real part = -2 & imaginary part = -5
b) 1) 6 + 4i
2) -12+ 5i
3) 5-14i
Answer:x^2-76
Step-by-step explanation:
Answer:
x < -3/4 OR x>16/5
Step-by-step explanation:
5x – 4 > 12 OR 12x+5 < -4
Solve the parts separately and then put back together
5x – 4 > 12
Add 4 to each side
5x-4+4>12+4
5x >16
Divide each side by 5
5x/5>16/5
x > 16/5
12x+5 < -4
Subtract 5 from each side
12x+5-5<-4-5
12x<-9
Divide each side by 12
12x<-9/12
x <-3/4
Put back together
x < -3/4 OR x>16/5
Answer:
F(-2)=2
Step-by-step explanation:
F(x)=4x+10
F(-2)
F(-2)=4(-2)+10
-8 +10
F(-2)= 2
