Check the picture below.
the volume of the prism will simply be the product of the triangular area and its length, it has a length of 8, thus

Standard Form is ax + by = c, where a, b, and c are not fractions and a is not negative.
So, you can go through each of your options to see which ones work with those rules.
A. 2.5x + 3y = 12 No, this is not in Standard Form. 2.5 can be rewritten as 2<span>

, menaing A is a fraction, which you can't have.
B. -10x - 3y = 1 No, this is not in Standard Form. A is -10, but A can't be negative.
C. 2x + 3y = 12 Yes, this is in Standard Form. It follows all of the rules.
D. 5x + 5y = 10 Yes, this is in Standard Form. It follows all of the rules.
So,
C and
D are both written in Standard Form.

Answer:
10
Step-by-step explanation:
=2.5(6*4)/6
=2.5*4(6 and 6 gets cancel)
=10
Sub f(x)=1 into equation
1=-5x-4
5=-5x
x=-1
Answer:
920 cm^2
Step-by-step explanation:
There are 2 rectangles in the overall shape, find the areas of each rectangle... The first one is 800 and the second is 120 then we add those to make the whole shape: 920!
