Answer:f=12.96
Step-by-step explanation:
f(-4.2)=3.25(-4.2)+22.41
f(-4.2)=-13.65+22.41
f(-4.2)=8.76
f=12.96
Answer: h(h-3)(h+4)
Step-by-step explanation:
To find the volume of rectangular-shaped box we will have to multiply the length by the width by the height.
Given the statements we can determine the length with the equation
L = h -3 where l is the length and h is the height.
the width can also be represent by the equation
w = h + 4
The height is is h and the length is h- 3 and the width is also h+4 so the expression will be h(h-3)(h+4)
72% as a fraction is 18/25.
Change 72% into a decimal, which is 0.75.
Then change the decimal into a fraction, 72/100.
Last step is to simplify 72/100 in its lowest form which gets us 18/25.
y=-3x+4
x=2y+6
y + 3x =4
-2 + =6
x= 2y +6
y+3.(2y+6)=4
7y = -14
7y=-14
y=-2
y=-2
x=2y+6
x=2(-2)+6=2
solution is {y,x}= {-2,2}
The other sides are 12cm and 5cm. This is a Pythagorean triple. It is useful to know them!!!
