x + 45
y + 9.46
Step-by-step explanation:
9x + 4.05xy + 15y + 30y - 11x + 9.46
4.05xy + 9x - 11x + 15y+ 30y+ 9.46

I hope this helps you
x= -1 f (-1)=(-1)^2+7=1+7=8
g (f (-1))= g (8)
x=8 g (8)= 8-4/8=4/8=1/2
Answer:
6.7
Step-by-step explanation:
Given is a right angled triangle.
So by Pythagoras theorem:
Length of the third side
Answer:
D
.(w)(2w+7)=85
Step-by-step explanation:
Hi, to answer this question we have to apply the next formula:
Area of a rectangle: width x length
Since the length will be 7 feet longer than twice its width (w).
So, to obtain the length we have to multiply the width by 2 (twice) and add 7.
Mathematically speaking:
Length: 2w+7
Back with the area formula:
Area of a rectangle: length x width
Replacing with the values given:
85 = w (2w+7)
Note: option D correct equation is D
.(w)(2w+7)=85, since we don't have x variables.
