The correct question is;
Layla wants to build a wooden box with a volume of 45 cubic centimeters. She started with a width of 3 cm and a height of 3 cm. How long should Layla make the box?
Answer:
Box is 5 cm long.
Step-by-step explanation:
We are given;
Volume; V = 45 cm³
Width; w = 3 cm
Height;h = 3 cm
Now, this box has the shape of a cuboid and the volume of a cuboid is given as;
V = l × w × h
Where;
L is length
w is width
h is height
Making L the subject, we have;
V/wh = L
Plugging in the relevant values to obtain;
L = 45/(3 × 3)
L = 45/9
L = 5 cm
1.
2x (4x² -3x +8) - (3x+4)
8x³ - 6x² +16x -3x -4
8x³ -6x² +13x -4
2.
3x(2x²-7)+7x(x²+4)
6x³ -21x +7x³ +28x
13x³ +7x
3.
2x² (-4x^4 -12x² - x +17)
-8x^6 - 24x^4 - 2x³ + 34x²
So we know that 2/3=fantasy
1/4=bio
so bio+fantasy=2/3+1/4
2/3 times 4/4=8/12
1/4 times 3/3=3/12
2/3+1/4=8/12+3/12=11/12
11/12 of 60 are bio or fantassy
mltiply
11/12 times 60=660/12=55
answer is 55
Answer:
-45 < x < 5 (see graph below)
Step-by-step explanation:
to isolate x by itself, subtract 20 from all three terms of the equation:
once you finish subtracting 20, x should be by itself, making the equation graphable:
since x is not equal to -45 or 25, the graph line endings have open circles.
