How would you find the area without the height of the triangle?

Step-by-step explanation:

It's an equaliteral triangle. Therefore, the height divides the base in half.

Use the Pyhagorean theorem:

         subtract 256 from both sides

The formula of an area of a triangle:

b - base

h - height

We have b = 32 ft and h = 12 ft. Substitute:

The formula of an area of a rectangle:

l - length

w - width

We have l = 32 ft and w = 26 ft. Substitute:

The area of the figure:

answer: 2x + 2 − 2 = 10 − 2; subtraction property of equality

step-by-step explanation:

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.
