Answer: $Area=5x^2+10x$

Step-by-step explanation:

The area of a rectangle:

$a=h$ × $w$

$a=5x(x+2)$

$a=5x$ × $x+5x$ × $2$

$a=5x^2+10x$

Find the slope, if it exists, of the line containing the points (-4,0) and (-5,3)

NNADVOKAT [17]

Answer:

Step-by-step explanation:

let (-4,0) be (x1,y1) and (-5,3) be (x2,y2)

slop formula = <u>y2-y1</u>

x2-x1

=(3-0)+(-5-(-4))

=3+(-5+4)

=3+(-1)

=3-1

The area of the base of a prism is 21 cm2. The perimeter of the base is 20 cm. The height of the prism is 8 cm.

mart [117]

The lateral area of the prism equals to height * perimeter of the base. So the lateral area is 160 cm2. And the surface area of the prism equals to the area of the base*2+the lateral area= 202 cm2.

Anna is swimming against the ocean current. The following equation models her speed: f(x) = x2 − 6x +1, where x is Anna's speed

REY [17]

Answer:

All real numbers

Step-by-step explanation:

we have the function

$f(x)=x^2-6x+1$

This is a vertical parabola open upward

The vertex represent a minimum

Remember that

The domain of a function is the set of all possible values of x

The quadratic functions are continuous and defined for all real values of x.

therefore

The domain of the function f(x) is the interval (-∞,∞)

That means

All real numbers
