a plat grows 1 mm per 10 years. How much does it grow in 2 decades. PLEASE HELP ME THIS IS SO DIFFICULT. BRAINIEST WILL BE GIVEN

2 mm

Step-by-step explanation:

a decade is 10 years

2 decades = 20 years

20/10 * 1 = 2

2 mm

Step-by-step explanation:

2 decades is the same as 20 years.

Therefore,

10 years -- 1 mm

20 years -- 2 mm

Thenks and mark me brainliest :))

answer rather than having to add and subtract the measurements of the semi-circle, notice that the semicircle to the left of ad is actually identical in area to the blank semicircle-shaped space to the left of bc. so if we transferred the red semicircle into the blank space, we would end up with a square of side length 24 cm. the area of a square is s^2 = 24^2 = 676 cm^2.

u also answered this so i think u would know but i am here to

put in or use mine

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
