Answer:

Ic² + b²l = 13 units.

Step-by-step explanation:

We have to evaluate the expression Ic² + b²l with unknowns b and c and having the values of b and c respectively - 3 and - 2.

Now, Ic² + b²l

= I(- 2)² + (- 3)²l {Putting the values of b and c}

= I4 + 9l

= I13l

= 13 units.

Therefore, Ic² + b²l = 13 units. (Answer)

How to calulate the area of a square with a perimeter of 60 inches

olasank [31]

Answer:

Step-by-step explanation:

The formula of an area of a square:

$A=s^2$

The formula of a perimeter of a square:

$P=4s$

<em />

We have a perimeter

$P=60\ in$

Substitute:

$4s=60$ <em>divide both sides by 4</em>

$\dfrac{4s}{4}=\dfrac{60}{4}\\\\s=15\ in$

Put it to the formula of an area of a square:

$A=15^2=225\ in^2$

Jim is a furniture salesman. his weekly pay is $300 plus3.5% of his total sales for the week.jim sell x dollar's worth of furnit

Lesechka [4]

For this case, the first thing we must do is define a variable.
We have then:
x: total sales for the week
We now write the equation that models the problem.
We have then:
p (x) = 0.035x + 300
Answer:
a function, p (x), which can be used to determine his pay for the week is:
p (x) = 0.035x + 300

Suppose that the functions f and g are defined for all real numbers x as follows.

Angelina_Jolie [31]

Answer:

$(f*g)(x)=2x^{2}-4x-30\\$

$(f-g)(x)=-(x+11)\\$

Step-by-step explanation:

the expression (f*g)(x) can be expanded as follows

$(f*g)(x)=f(x)*g(x)\\$

since $f(x)=x-5,g(x)=2x+6$

Hence

$(f*g)(x)=f(x)*g(x)\\(f*g)(x)=(x-5)*(2x+6)\\(f*g)(x)=2x^{2}+6x-10x-30\\(f*g)(x)=2x^{2}-4x-30\\$

also the expansion for (f-g)(x) is express as

$(f-g)(x)=f(x)-g(x)\\$

also since

$f(x)=x-5,g(x)=2x+6$ then when we substitute values, we have

$(f-g)(x)=(x-5)-(2x+6)\\(f-g)(x)=x-5-2x-6\\(f-g)(x)=-x-11\\(f-g)(x)=-(x+11)\\$

For this type of operation kindly note the below expansions

$(f*g)(x)=f(x)*g(x)\\$

$(f-g)(x)=f(x)-g(x)\\$

$(f+g)(x)=f(x)+g(x)\\$

$(f/g)(x)=f(x)/g(x)\\$

Carl Dove 617.3 miles his car gets about 41 miles per gallon.which is the best estimate of how many gallons of gas Carl used

mrs_skeptik [129]

Well if his car goes 617.3 miles, and he goes 41 miles per gallon

what the gallons will be

divide 617.3 by 41
=15.056

so his car used ~ 15.06 gallons of gas (i rounded the answer, if you want, you can put the full thing)

I hope this helps
