X^2 and 5x both have x in common to factor out. To add or subtract them, 5x^2 is the least common denominator .
Answer:
The answer are A and D
Step-by-step explanation:
A) A part of a line
and
D) Has only one endpoint
f = 2
Simplify both sides of the equation <span><span>1.25f</span>+2</span>=<span><span>−<span>2.75f</span></span>+<span>10
Add 2.75 to each side </span></span><span><span>4f</span>+2</span>=<span>10
Subtract 2 from both sides </span><span>4f</span>=<span>8
Divide each side by 4 </span>f=<span>2</span>

Answer:
800
Step-by-step explanation:
We can set up a proportion using the information we are given. We know that 240 students corresponds to 30% and that the total number of students, x, corresponds to 100%
Cross multiply and solve:
240 * 100 = 30x
24000 = 30x
800 = x
Ax-6=dx -8
ax-dx =-2
X(a-d)=-2
x=-2/(a-d)
