Answer:
½
Step-by-step explanation:
we know y=mx+h
y= ½ x + 6 so m=½
Answer:
20x²-3x-2
Step-by-step explanation:
(4x+1)(5x-2)
20x²-8x+5x-2
20x²-3x-2
Answer:
a)HCF between 774&252 is=18
LCM between 774&252=10836
b)HCF between 204&544 is=68
LCM between 204&544 is=1632
c)HCF between 770&385 is=385
LCM between 770&385 is =770
d)HCF between 477&552=3
LCM between 447&552 is =82248
Step-by-step explanation:
a)because LCM=2×2×3×3×7×43
b)because LCM=2×2×2×2×2×3×17
c)because LCM=2×5×7×11
d)because LCM=2×2×2×3×23×149
Okay, so basically we have:
w as width; and 6+w as length
Perimeter=2w+2l
just substitute it with the values of width and length
P=2w+2(6+w)
P=2w+12+2w
P=4w+12
So, the answer is letter B.

- subtract the 12 from both sides so that it becomes the last constant term in the quadratic equation which should now equal 0.
- take the 4x
- half the coefficient of 4 (2)
- square it (4)
- add it to the equation (+4)
- subtract it from the equation (-4)
- factorise the square (x+2)^2 expands to (x^2 + 4x + 2) as {a+b}^2={a^2 + ab + ba + b^2}
- now the equation is in turning point form.
- to find x, add 16 and square root 16 and (x+2)
- subtract 2 from positive or negative 4 (as -4^2 and 4^2 both equal 16).
- This should give you two values for x, -6 and 2.
I really hope that this helped :)
