Answer:
c = 
Step-by-step explanation:
To make a perfect square
add ( half the coefficient of the x- term )² to x² + 5x
x² + 5x + (
)²
= x² + 5x + 
= (x +
)² ← a perfect square
Answer:
1200 N
Step-by-step explanation:
Newton's second law:
F = ma
F = (300 kg) (4 m/s²)
F = 1200 N
Step-by-step explanation:
1. vertical angles. x = 5
2. supplementary x = 12
3. complementary x = 7
4 Supplementary x = 17
5. sQR = 118
RQT = 62
6 LNK = 47, JNM = 47
Answer:
F
Step-by-step explanation:
1m = 100cm
0.8m = 100*0.8 = 80cm
Answer:
y = 2x - 1
Step-by-step explanation:
None of those would be correct, the line on the graph is y = 2x - 1 because the slope of the line is 2 and the y -intercept -1.
You can also check, we know that on the graph the coordinates where the dots are located are: (2,3),(3,5),(4,7) where the first number is x and second is y coordinate.
Check answer:
Let x=2 if this is correct y should be equal to 3 because of the first point (2,3).
y = 2(2)-1 = 4 - 1 = 3
check the other points if you want to confirm.
