It could be just 4x^2-12=0?
<h3>
Answer: x = 4</h3>
==================================================
Explanation:
Use the remote interior angle theorem. This says a pair of interior angles always add to the measure of the exterior angle that is not adjacent to any of the interior angles, so basically what your diagram is showing.
(interior angle C) + (interior angle D) = exterior angle
(46) + (-1+8x) = 18x+5
8x+45 = 18x+5
8x-18x = 5-45
-10x = -40
x = -40/(-10)
x = 4
The total weight of 4 dolls and 3 plush toys is 11 oz
Let's say the dolls weigh 2 oz and the plush toys weigh 1 oz
2-4= 8 1x3 =3
8+3=11
Then 2 dolls =4 and 3 plush toys= 3
Weight should be 7oz
Plus the weight of the box 1
Total= 8 not 10
Answer:
Total paper required to wrap the gift without any overlaps:
Step-by-step explanation:
Here, we need to find the total paper required without any sides overlapping to wrap the gift.
The gift is of <em>cuboid </em>type.
Given the following:
<em>Length </em>= 15 cm
<em>Width </em>= 30 cm
<em>Height </em>= 20 cm
Please refer to the attached figure.
We can infer that to find the paper required, we actually need to the find the<em> total surface area of the cuboid</em>.
Because the gift wrap will be done <em>on the faces of gift</em> (which is of cuboid shape).
Formula for Surface Area of <em>Cuboid:</em>
Hence, total paper required to wrap the gift without any overlaps:
I think i did it wrong but 1980 is what i got...i am unsure. hope that helped though:)
