The measure of 2 base angles on the same side of the trapezoid are 10x + 7 and 6x – 3 respectively. what is the measurement of the larger base angle?
select one:
a. 16
b. 67
c. 117
d. 147

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.
