HELP!

I’m having a hard time solving this.

Log x + log (x+15)=2

The expression represents the sum of the holes.

The variable in the expression is Mia's age.

The simplified expression is 4x - 6

The constant in the simplified expression is -6.

An expression in mathematics is a sentence that is made up of at least of two numbers or variables and has at least one mathematical operation in it.  An expression does not have an equal to sign (=). An example of an expression is 2 + x .

A constant is a value in an expression that never changes in value. For example, in the expression 2x + 5x, 2 is the constant.

Mia's holes = x

Isabelle's holes = 2x - 16

Erick's holes = 10 + x

Sum of holes = x + 2x - 16 + 10 + x

To simplify, add similar terms together : 4x - 6

Answer:

“the product of 6.2 and the sum of 3c and 8'' will be algebraically represented as:

⇒ (6.2) (3c + 8)

We know that the numbers that we multiply are the factors of the product.

Here, (6.2) and (3c+8) are the factors of the expression.

Step-by-step explanation:

Let us breakdown and translate the word expression into an algebraic expression.

The sum of 3c and 8 is algebraically represented as:

⇒ 3c + 8

Thus,  “the product of 6.2 and the sum of 3c and 8'' will be algebraically represented as:

⇒ (6.2) (3c + 8)

We know that the numbers that we multiply are the factors of the product.

Here, (6.2) and (3c+8) are the factors of the expression.

Point Form:

(4,−12)(4,-12)

Equation Form:

x=4,y=−12

Answer:

L = 3x - 2

P = 6x - 10

Step-by-step explanation:

Area = length * width

A = l*w

so if the width is 6 inches we can say w = 6

and we can say that l = to the length of the rectangle

if we substitute this:

(18x - 12) = l * 6

we get the answer l = 3x - 2 since we divide both sides by 6.

the expression for length of the rectangle is -> l = 3x - 2

for the perimeter:

P = 2(l + w)

if we substitute this:

P = 2(3x - 2) + 6

distributive property:

P = 2(3x) - 2(2) + 6

then would be:

P = 6x - 4 + 6

(combine like terms) -> P = 6x - (4 + 6)

then you would get: P = 6x - 10

which can also be writtern as -> P = 6x + (-10)

but this is not simplified so you would just write it as 6x - 10

Answer:

A - a = 4, b = -3, c = 3

Step-by-step explanation:

When you substitute in a, b, and c you get

(2x - 5) (x + 2) + (4x^2 + -3x + 3)

collect like terms

(2x)(x) + (2x)(2) + (−5)(x) + (−5)(2) + 4x^2 + −3x + 3

combine like terms

2x^2 + 4x + −5x + −10 + 4x^2 + −3x + 3

(2x^2 + 4x^2) + (4x + −5x + −3x) + (−10 + 3)

6x^2 + −4x + −7

6x^2 + −4x −7

The unit rate is 22.5 cents per oz .

The unit rate of any quantity is calculated by dividing (total cost) with (total units purchased).

For Example : If 12 bananas cost $120 then 1 banana will cost 120/12=$10.

In the given question

16oz bottle costs $3.59.

As we have to find the unit rate in cents per oz , we first convert $3.59 to cents.

We know that

$1=100cents

$3.59=100*3.59

=359cents

So the price of 16 oz bottle = 359 cents

Unit rate = (total price ) / (units purchased)

Substituting the total price as 359 cents and units purchased as 16oz.

Unit rate = 359/16

=22.4375

≅22.5

Therefore , the unit rate is 22.5 cents per oz.

Answer:

87, if it were 45 degrees,  it would be 90, closest to 90 is 87

Answer:

87 feet

Step-by-step explanation:

We have an angle that's 44 degrees and we know that Susan is 90 feet from the base of the tree. We need to know the height of the tree, which is the value opposite from the angle we know.

Use tangent to find height.

tan (44) = x / 90   then multiply both sides by 90

x = tan (44) * 90   evaluate tan(44) and substitute into the equation

x = 86.911

round to nearest whole foot: 87 feet

Answer:

43/24

Step-by-step explanation:

The solving steps are as follows:

Answer:

43/24

Step-by-step explanation:

LCM of 6 and 8 = 24

[tex]\sf \dfrac{-3}{8}=\dfrac{-3*3}{8*3}=\dfrac{-9}{24}\\\\\\\dfrac{13}{6}=\dfrac{13*4}{6*4}=\dfrac{52}{24}\\\\\\\dfrac{-3}{8}+\dfrac{13}{6}=\dfrac{-9}{24}+\dfrac{52}{24}[/tex]
