Answer:

5, 29 will both blank boxes

Step-by-step explanation:

the product of (4z^2 + 7z – 8) and (–z + 3)

(4z² + 7z – 8)(–z + 3)

-z(4z² + 7z – 8) + 3(4z² + 7z – 8)

-4z³-7z²+8z+12z²+21z-24

choose like terms

-4z³-7z²+12z²+8z+21z-24

-4z³+5z²+29z-24

5, 29

In the equation 0.75s-5/8 = 44, how do you combine the like terms?

garri49 [273]

Answer:

Step-by-step explanation:

In the given equation, the "like terms" are the constants 5/8 and 44.

It simplifies the math if we eliminate the fractions first. Note that 0.75 = 6/8, so now we have:

8(6/8)s - 8(5/8) = 44).

Multiplying all three terms by 8 (above) yields

8(6s) - 8(5) = 8(44), or

48s = 8(44 + 5), or 48s = 8(49)

Dividing both sides by 48 yields s: s = 8(49/48)

Review "like terms:" These are terms that have at least one characteristic in common. 5/8 and 44 are like terms because they are only constants (no variables are present). We must add 5/8 and 44. 0.75s does not have a "like term" in the given equation.

The edge length of cube A is two times the edge length of cube B. How many times greater isthe volume of the cube A than the vol

allsm [11]

Answer:

<h2>8 times greater</h2>

Step-by-step explanation:

The formula of a volume of a cube:

$V=a^3$

a - edge length

-----------------------------------

The edge length of cube B is a.

The edge length of cube A is 2a.

Calculate the volumes:

$V_A=(2a)^3=2^3a^3=8a^3\\\\V_B=a^3$

How many times greater is the volume of the cube A than the volume of cube B?

Make the quotient:

$\dfrac{V_A}{V_B}=\dfrac{8a^3}{a^3}=8$

The digit \greenD88start color #1fab54, 8, end color #1fab54 in which number represents a value of 888 thousandths?

Arte-miy333 [17]

<em>Question:</em>

<em>The digit 8 in which number represents a value of 8 thousandths? </em>

Answer:

See Explanation

Step-by-step explanation:

The question requires options and the options are missing.

However, the following explanation will guide you

Start by representing 8 thousandths as a digit

$\frac{8}{1000} = 0.008$

i.e.

8 thousandths implies 0.008

Next;

Replace the 0s with dashes

_ . _ _8

Note that there are two dashes after the decimal point and before 8

PS: The dashes are used to represent digits

This implies that thousandths is the 3rd digit after the decimal point

Typical examples to back up this explanation are:
