Answer:
x = 4
Step-by-step explanation:
we know that 72 and (2x + 10) add up to 90
90-72 = 18
(2x + 10) = 18
2x = 8
x = 4
ANSWER
A) 9.4 * 10^-8, 9.25 * 10^-6, 2.5 * 10^3, 7* 10^3
EXPLANATION
The numbers are given in standard form.
The first criteria we will use to order them is the exponents.
The bigger the exponents the bigger the number.
The second criteria is that, if the exponents of any two numbers are the same, then we use the numbers multiplying the powers of 10 to order.

The correct choice is A.
Hello!
To find the surface area you can divide the prism into the 2D shapes it is made of
First list out all the shapes
2 triangles with bases of 18 and heights of 15.6
3 rectangles with side lengths of 20 and 18
First find the area of the triangles
The equation to find the area of a triangle is

A is area
h is height
b is base
Put in the values you know

Solve
A = 140.4
The triangles have an area of 140.4 units
Next we find the area of a the rectangles
To do this we multiply the sides
18 * 20 = 360
The rectangles have areas of 360 units
Now we add all the areas
There are 2 triangles and 3 rectangles
140.4 + 140.4 + 360 + 360 + 360 = 1360.8
The answer is B) 1360.8cm squared
Hope this helps!
Answer: Yes
Step-by-step explanation:
I am not sure if this is correct, but a kilogram is a very small unit of measure. I would assume that it is greater since 1000kg is equal to 1g. The oranges would have to weigh almost nothing for it to be less than $6.
