Area = length times width

A = (3x^2 - 4x + 6)(x - 6)

A = 3x^3 - 4x^2 + 6x - 18x^2 + 24x - 36

A = 3x^3 - 22x^2+ 30x - 36

Done!

At least they admitted this is algebra not geometry. You'll get the same question next year but they'll call it geometry.

The area is the product of the sides:

$A=(x-6)(3x^2-4x+6)$

We just distribute and collect terms:

$A=x(3x^2-4x+6) - 6(3x^2-4x+6)$

$A=3x^3-4x^2+6x - 18x^2 +24x -36$

$A=3x^3- 22x^2+30x-36$

Answer: 3rd choice

Jackson estimated 637 ÷ 78 as 640 ÷ 80. He reasoned that 64 tens divided by 8 tens should be 8 tens. Is Jackson’s reasoning corr

Sholpan [36]

Answer:

the correct solution has been explained

Step-by-step explanation:

Jackson,s reasoning is incorrect because it should be 8 ones and not 8 tens that would give 64

$\frac{640}{80} = \frac{64}{8} = 8$

Moreover, $\frac{637}{78} is\ not\ equal\ to \frac{640}{8}$

as $\frac{637}{78}= 8.16$

whereas $\frac{640}{80}$ = 8

clearly, both quantities are different
