Answer:2x+2
Step-by-step explanation:
Answer:
Less than, at max, greater than, at least
Or,
Not greater/more than, not less than
To answer the problem above, I assumed the object to be a rectangular prisms. To solve for the volume of such figures, multiply all three dimensions. This is mathematically expressed as,
V = H x D x L
V = (1.5 ft) x (4 ft) x (2 ft) = 12 ft^3
The volume of the object is 12 ft^3. Thus, the answer is letter A.

Answer: 280</h3>
Work Shown:
x = number of students in the 6th grade class
30% = 30/100 = 0.30
30% of x = 0.30x this is equal to 84 since "30% of the 6th graders are boys (and there are 84 boys in sixth grade)", so we say 0.30x = 84
Divide both sides by 0.30 to isolate x
0.30x = 84
0.30x/0.30 = 84/0.30
x = 280
So there are 280 students overall in the 6th grade class.
Answer:
x - 1 and 5x - 7
Step-by-step explanation:
f(x) + g(x)
= 3x - 4 - 2x + 3 ← collect like terms
= x - 1
f(x) - g(x)
= 3x - 4 - (- 2x + 3) ← distribute parenthesis by - 1
= 3x - 4 + 2x - 3 ← collect like terms
= 5x - 7
