Consider ways to multiply to get 42. Then see if the numbers can be used to make -27.

42 = 21 × 2...not going to work.
42 = 14 × 3...not going to work. (Though -14 and -3 add to -<em>17</em>)
42 = 7 × 6...not going to work.

There are no whole number solutions to this question.

SOVA2 [1]
The formula of pyramid:
v =  \frac{1}{3} ah
Where v is the volume, a is the base area and h is the height.

We can then put the given information into the formula:

176 = (1/3)(3x × x)(11)

(176 × 3) / 11 = 3x^2

3x^2 = 48

x^2 = 48/3

x = _/16

x = 4

Laura picks 7 apples.Some apples are red and some are green. Fewer than 4 of the apples are red. How many of laura's apples coul
GrogVix [38]

Answer:

As many as 7 apples or as few as 4 apples could be green.

Step-by-step explanation:

Laura picks 7 apples.Some apples are red and some are green. Fewer than 4 of the apples are red. How many of laura's apples could be green?​

x = total number of red apples

y = total number of green apples

Fewer than 4 of the apples are red.

x<4

That means that 3 or less of the apples are red

So, 7 - 3 = 4

That means that 4 or more apples are green.

7≥y≥4

That means that as many as 7 apples or as few as 4 apples could be green.

We have that
y=6^x
we know 
to find the inverse
replace x with y and y with x,
x=6^y

we know that
y=logb(x)----------> x=b^y

therefore
x=6^y---------------> y=log6(x)

the answer is the option A.) Y=log 6x
