Step-by-step explanation:
26. x²+5x+25/4 = (x + 5/2)²
29. x²/4y²-2/3+4y²/9x² = (x/2y - 2y/3x)²
Answer:
Step-by-step explanation:
This is simple, the picture that is provided tells us the answer easily.
An angle lower than 90 degrees is called an acute angle. While one that is the same as 90 degrees is a right angle, and one that is more than 90 is obtuse.
We are asked to take a look at angle 4, we can see that is more than 90 degrees. Since 100 is the only answer with an amount higher than 90 degrees and fits the angle, it is the angle.
25/80 + 24/80 = 49/80. 16 and 20 both go into 80. !6 goes in 5 times so you multiply 5 by 5. 20 goes into 80 4 times so you multiply 4 by 4. 24/80 + 25/80 = 49/80.
Answer:
C
Step-by-step explanation:
Floyd's contract consists of
(i) $200 per month fixed.
(i) $12 per album sold.
Let x = number of albums sold last month.
Because total earnings is $644, therefore
200 + 12x = 644
To find x, do the following:
Subtract 200 from each side.
12x = 644 - 200 = 444
Divide each side by 12.
x = 444/12 = 37
Answer:
The equation is 12x + 200 = 644.
The solution for x (number of albums sold) is 37.
