Answer:
28
Step-by-step explanation:
Square: 4 * 4 = <u>16</u>
Small Triangle: 1 * 4 = 4 / 2 = <u>2</u>
Large Triangle: 5 * 4 = 20 / 2 = <u>10</u>
<u>16 + 2 + 10</u> = 28
Answer:
You have to see for yourself on the picture we cannot see. But from these statements alone it's either the second or the fourth option.
Step-by-step explanation:
They are perpendicular because their slopes are equal - Doesn't make sense, they would be parallel not perpendicular
They are perpendicular because their slopes are negative reciprocals - Makes sense
They are not perpendicular because their slopes are equal - Makes sense but it does not explain their relationship as well as the statement above
They are not perpendicular because their slopes are not negative reciprocals - Makes sense since that's how perpendicular lines work.
Conclusion, since we can't see the lines. You have to see for yourself on the picture we cannot see. But from these statements alone it's either the second or the fourth option.
If you add a picture I can narrow it down.
Answer:
a rational number is an expression in which the numerator and denominator are polynomials. this is useful to know because often polynomials can be factorized. besides, if there is a variable in the denominator, there will be one or more restrictions.
example: (4x²-25)(2x+5) is simplified to 2x-5 with restrictions x≠-5/2
Answer:
(x + 5)2 + 2 = 42.5
List of steps
2(x)+2(5)
2x+10
2x+10+2=42.5
2x+12=42.5
2x=42.5-12
2x=30.5
2x/2=30.5/2
x=30.5/2
x=15.25
x=15.25
Step-by-step explanation:
(x + 5)2 + 2 = 42.5
Solve (x+5)2 first
2(x)+2(5)
2x+10
Now the equation
2x+10+2=42.5
2x+12=42.5
Make 2x the subject
2x=42.5-12
2x=30.5
Divide both sides of the equation by 2
2x/2=30.5/2
x=30.5/2
x=15.25
