Combine like terms to create an equivalent expression. 7.4z−5(−1.6z+2.4)

ryzh [129]

Answer: $15.4z-12$

Step-by-step explanation:

For this exercise it is important to remember:

The Distributive property:

$a(b\±c)=ab\±ac$

The multiplication of signs:

$(+)(+)=+\\\\(-)(-)=+\\\\(-)(+)=-$

Then, given the following expression:

$7.4z−5(-1.6z+2.4)$

You need to apply the Distributive property. Then:

$=7.4z+8z-12$

Now you can combine like terms (or add the like terms). Then you get:

$=15.4z-12$

Therefore, the equivalent expression created by combining like terms, is:

$15.4z-12$

The product of the first three terms of a geometric progression is 3375, and their sum is 65. Find the first term of this progre

artcher [175]

Answer:

5 or 45

Step-by-step explanation:

If the first term is "a" and the common ratio is "r", then the first three terms are ...

a, ar, ar²

Their product will be ...

a × ar × ar² = (ar)³ = 3375

ar = ∛3375 = 15

Their sum will be ...

a + ar + ar² = 65 = 15/r + 15 + 15r

Subtracting 15 and multiplying by r/5, we have the quadratic in r:

10r = 3 + 3r²

3r² -10r +3 = 0 . . . . in standard form

(3r -1)(r -3) = 0 . . . . factored

r = 1/3 . . or . . 3 . . . . values of r that make the factors zero

The first term is 15/r = 45 or 5

_____

The first three terms could be 5, 15, 45; or they could be 45, 15, 5.
