(7x + 2 + 8x^4) – (2x – 5 – 8x^4) + (3x + 5x^4)
= 7x + 2 + 8x^4 – 2x + 5 + 8x^4 + 3x + 5x^4
= 8x + 7 + 21x^4
= 21x^4 + 8x + 7
Answer:
prism
Step-by-step explanation:
because it is a rectangle but it will form into a rectangular prism.A cube is a 3d square .while a rectangle is a 2d figure,while a cylinder is a 3d circle
The term circular mil is common in expressing the cross sectional area of a wire. Electrical wires have very minute diameters that are often measured a thousandth of an inch. Hence, when you find the area of the circular wire, for convenience, the unit used is circular mil which is equivalent to one-thousandth of an inch.
For example, a wire has a diameter of 6×10⁻⁵ inches. To find its area:
A = πr² = π( 6×10⁻⁵ /2)² = 2.83×10⁻⁹ in²
Since 1 mil = 1/1000 (inch) or 0.001 inch
A = (2.83×10⁻⁹ in²)* (1 mil/ 0.001 inch)²
A = 0.00283 circular mils
<span>3/8 of the animals are birds<span>
of the birds: 4/15 are birds of prey
If you want to know what fraction of the animals
at the zoo are birds of prey, you can calculate this using the following steps:
4/15 * 3/8 <span>= 12 / (15*8) = </span>1 / (5*2) <span>= </span>1 / 10 = 0.1
<span>Result: In the town zoo, </span>1/10 of animals are birds of prey<span>.</span></span></span>
The total number of stickers the 2 children had was 192 stickers.
Let x represent Mary initial stickers, y represent Gary initial stickers and z represent the total stickers.
x + y = z
They shared in the ratio of 5:3, hence:
x = (5/8)z
Mary gives 1/3 of her stickers to Gary to have 32 more stickers than her.
(1/3)x = (1/3)(5/8)z = (5/24)z
y + (1/3)x = (2/3)x + 32
Solving equation 1, 2 and 3 gives:
x = 120, y = 72, z = 192
The total number of stickers the 2 children had was 192 stickers.
