Answer:
Step-by-step explanation:
<u>Sides of the picture added margin:</u>
<u>Solution</u>:
- A(margin) = Total area - A(picture)
- (8 + 2x)(5 + 2x) - 5*8 = 30
- 4x² + 10x + 16x + 40 - 40 - 30 = 0
- 4x² + 26x - 30 = 0
- 2x² + 13x - 15 = 0
- x = (-13 + √(13² + 2*4*15))/4
- x = (-13 + 17)/4
- x = 1 cm
Note. The other root is ignored as negative.
Answer:
1.)-8
2.)-5
3.)4
Step-by-step explanation:
So, the function f(x)=3x-5
The questions say "If you were to substitute these numbers what answer would you get?"
Understanding this,
First question is with x=-1
f(-1)=3(-1)-5
f(-1)=-3-5=-8
_____________________________________
f(0)=3(0)-5
f(0)=0-5=-5
_____________________________________
f(3)=3(3)-5
f(3)=9-5=4
V=LWH
L=8
W=7
H=5
V=8*7*5=280 in^3
you need 280 in^3 of water
