Answer:
12x^2+2x+7
Step-by-step explanation:
Distribute the Negative Sign:
=4x^2+6+7+−1(−8x^2−2x+6)
=4x^2+6+7+−1(−8x^2)+−1(−2x)+(−1)(6)
=4x^2+6+7+8x^2+2x+−6
Combine Like Terms:
=4x^2+6+7+8x^2+2x+−6
=(4x^2+8x^2)+(2x)+(6+7+−6)
=12x^2+2x+7
Answer:
Step-by-step explanation:
Here, we have to find the value for h, in terms of .
Assuming The equation is:
We cross multiply to get:
Now, we divide both sides by to get an expression of h in terms of :
To do this you need to multiply how many centimeters long the drawing is times the number of meters per centimeter used in the scaling.
12 x 250 = 3000
£770.64
Step-by-step explanation:
100%=£754.79
10%=£75.479
1%=£7.5479
0.1%=£0.75479
1%+1%=2% (£7.5479+£7.5479=£15.0958)
2%+0.1%=2.1% (£15.0958+£0.75479=£15.85059)
2DP=£15.85
100%+2.1%=102.1% (£754.79+£15.85=£770.64)
