Step-by-step explanation:

V = Volume of cube

a = edge

Formula of volume of cube:

V = a³

1331 =  {a}^{3}  \\  \sqrt[3]{1331}  = a \\ a = 11

The length of each edge is 11 cm.

Show work and solve for √ ( 5 x − 9 ) − 1 = x.
Mandarinka [93]

sqrt (5x - 9) - 1 = x

sqrt(5x - 9) = x + 1

Square both sides:_

5x - 9 = x^2 + 2x + 1

x^2 - 3x + 10 = 0

(x - 5)(x + 2) = 0

x = 5 or -2.

Lets look for for any extraneous solutions:-

x = 5 ;  sqrt (5*5-9) - 1 = sqrt16 - 1 =  3  and  x = 3  (right hand side of equation)

so x = 5 is a solution

x = -2:  sqrt(5*-2 - 9) - 1 =  sqrt (-19) - 1  and x = -2  so this is extraneous

Answer:- One solution x = 5

What is the simplified expression for 3 y squared minus 6 y z minus 7 + 4 y squared minus 4 y z + 2 minus y squared z? y squared
tresset_1 [31]

Answer:

7y^2 - y^2z - 10yz-5

C. 7 y squared minus y squared z minus 10 y z minus 5

Step-by-step explanation:

A. y squared minus y squared z minus 10 y z minus 5

B. y squared minus y squared z minus 5 y z minus 5

C. 7 y squared minus y squared z minus 10 y z minus 5

D. 7 y squared minus y squared z minus 2 y z minus 5

Given:

3y^2 - 6yz - 7 + 4y^2 - 4yz + 2 - y^2z

Collect like terms in the expression

3y^2 + 4y^2 - 6yz - 4yz - y^2z - 7 + 2

Simplify

7y^2 - 10yz - y^2z - 5

Rewritten as

7y^2 - y^2z - 10yz-5

Option C. 7 y squared minus y squared z minus 10 y z minus 5

Is the answer

What is the factored form of the trinomial
worty [1.4K]

Answer:

which pair of numbers has a product of ac and a sum of b

ac = (-5)(-3)

sum = -8

x^2 - 5x - 3x + 15

x(x-5)-3(x-5)

(x-3) (x-5)

x=3 x=5

what is the factored form of the trinomial = (x - 3) (x - 5)

2. Factor the following:

x^2 - 8 x + 15

The factors of 15 that sum to -8 are -3 and -5. So, x^2 - 8 x + 15 = (x - 3) (x - 5):

Answer:  (x - 3) (x - 5)

Step-by-step explanation:

The quotient of a number and eight increased by twice the number
alexandr1967 [171]

Answer:

(x/8) + (2x)

Step-by-step explanation:

Let "a number" & "the number" (as they mean the same number) = x

"The Quotient" (meaning divide) of "a number and eight" = x/8

"increased by" (adding) by "twice the number" = + 2x

(x/8) + (2x) is your answer

Many points!! Answer asap
Semmy [17]
Remember
(ab)/c=a(b/c)
and
b/b=1 when b=b


1.
8+9t+4=
8+4+9t=
12+9t=
9t+12

2. (56ab)/b=56a(b/b)=56a(1)=56a

3. divising negatives yeilds positive
