Multiply each throughout!
=x^2+6x+8x+48
then arrange accordingly
x^2+14x+48
remember that in quadratic equation that you should have a squared (a) variable and a coefficient(b) and just a raw value (c)
A. The ratio of the person's shadow to their height is 6:2 or 3:1, so the height of the shadow is 360/3 or 120 m.
B. The model car's length divided by the ratio to the real car, which is 8.5/0.8 = 10.625 cm long.
In the expression 4 to the power of 9, the number 9 is called the D. exponent.
Number four here is the base, and the exponent is always shown as a superscript to the right of the base. It shows how many times you are supposed to multiply the base by itself.
