The product of 2 more than 3 times a number and 6 less than 4 times the number (z)

Rom4ik [11]

Answer:

$12z^{2} -10z -12$

Step-by-step explanation:

Let the number be z

2 more than 3 times z ==> 3z + 2

6 less than 4 times z ==> 4z - 6

Product of the above two is
$(3z + 2) (4z - 6) \\= (3z)(4z) + (3z)(-6) + (4z)(2) + (2)(-6)\\= 12z^{2} -18z + 8z - 12\\= 12z^{2} -10z -12$

Number 2 says Write the given equation in exponential form. Log8 1/512=-3

MA_775_DIABLO [31]

In exponential form it is given as, 8⁻³ = $$\frac{1}{512}$

Step-by-step explanation:

We have to write the given equation in the exponential form, that is in the form of base to the power value.

Given:

log₈ ( $$\frac{1}{512}$ ) = -3

Here the base is 8.

In the exponential form, it is written as,

base to the power 3 = 512

Here the reciprocal of 512 is given, so,

base to the power -3 = $$\frac{1}{512}$

So the exponential form is given as, 8⁻³ = $$\frac{1}{512}$

Evan enjoys eating fresh fruits and vegetables. This

Arlecino [84]

Answer:

$2304 \ in^3$

Step-by-step explanation:

Given the surface dimensions of the garden as 24 inches by 48 inches:

#Calculate surface area of the garden's top:

$A=lw\\\\=48\times 24\\\\=1152 in^2$

Given the soil's thickness is 2 Inches, we multiply this thickness by the garden's surface area to get volume of soil used:

$V=tA, t-thickness, A=Area=1152 \ in^2\\\\=2 \ in \times 1152\ in^2\\\\=2304 \ in^3$

Hence, the amount of soil used is 2304 cubic inches.
