Hi there!
Answer:
<u><em>=4x</em></u>
Step-by-step explanation:
Distributive property: ⇒ a(b+c)=ab+ac
You had to add similar elements.
9x-5x=4x
5x+4x=9x
9x-4x=5x
final answer: =4x
Hope this helps!

The y intercept is 2.25 and x intercept is -3
Answer:
30 cubes
Step-by-step explanation:
To find the number of small cubes in the larger cuboid, you can multiply the number of cubes that make up the length, width and height together.
There are 5 cubes along the bottom, 2 along the side and 3 going up. The volume would be 5 × 2 × 3 which is 30 cubes.
Hope this helps!
Answer:
1/6
Step-by-step explanation:
gradient= change in y/ change in x
-4--5/2--4= 1/6
1/6 is the gradient
Answer:
Your number is (3 sqrt(2)) / sqrt(2) = 3, and is a rational number indeed. I don't know exactly how to interpret the rest of the question. If r is a positive rational number and p is some positive real number, then sqrt(r^2 p) / sqrt(p) is always rational, being equal r. Possibly your question refers to situtions in which sqrt(c) is not uniquely determined, as for c negative real number or complex non-real number. In those situations a discussion is necessary. Also, in general expressions the discussion is necesary, because the denominator must be different from 0, and so on.
