96 ft2
can't be determined
What is the area of the figure? 40 ft2 84 - 1

Answers

Answer 1
Answer:

Answer:

A=80\ ft^2

Step-by-step explanation:

we know that

The area of the figure is equal to the area of an isosceles triangle (has two equal sides) plus the area of a rectangle

step 1

Find the area of the triangle

The area of the triangle is equal to

A=(1)/(2)bh

we have

b=16\ ft

To find out the height of the triangle Apply the Pythagorean Theorem

10^2=(16/2)^2+h^2

solve for h

100=64+h^2

h^2=100-64

h^2=36

h=6\ ft

Find the area of triangle

A=(1)/(2)(16)(6)

A=48\ ft^2

step 2

Find the area of rectangle

The area of rectangle is equal to

A=LW

we have

L=16\ ft\nW=2\ ft

substitute

A=(16)(2)=32\ ft^2

step 3

Find the area of the figure

Adds the areas

A=48+32=80\ ft^2

A carpenter has two plank of wood. One plank is xcm long, the other plank is 3xcm long. What is the total lenght of the two planks

Answers

The total length of the two plank is 4x cm

What is addition?

Addition in maths is a process of combining two or more numbers.

Given that, A carpenter has two planks of wood. One plank is x cm long, the other plank is 3x cm long.  

To find the total of the length of the plank, we will have to add their lengths,

Therefore, total length = 3x+x = 4x

Hence, the total length of the two plank is 4x cm

What is the formula for V=lwh for h

Answers

remember, you can do anythingn to an equaiton as long as you do it to both sides (except divide by zero)

solve for h
V=lwh
divide both sides by lw
V/(lw)=h

The formula for the volume of a cube is V(s) = s3 where s is the side length of the cube. What is the domain and range of this function?A.) s < 0, V(s) < 0
B.) s > 0, V(s) < 0
C.) s < 0, V(s) > 0
D.) s > 0, V(s) > 0

Answers

Answer:

Option D. s> 0, V(s)> 0

Step-by-step explanation:

we know that

The volume of a cube is equal to

V(s)=s^(3)

where

s is the side length of the cube

Remember that

The side length of the cube cannot be a negative number

so

s> 0

The domain is all real numbers greater than zero

The volume of the cube cannot be a negative number

so

V(s)> 0

The Range is all real numbers greater than zero
The domain is all the positive values and the range is also all the positive values.

Then the answer is the option D) s>0 and V(s) > 0.

X+9/x^3-9x^2+15x+25
how do I solve this

Answers

(x + 9)/(x^(3) - 9x^(2) + 15x + 25)
(x + 9)/(x^(3) - 10x^(2) + x^(2) + 25x - 10x + 25)
(x + 9)/(x^(3) - 10x^(2) + 25x + x^(2) - 10x + 25)
(x + 9)/(x(x^(2)) - x(10x) + x(25) + 1(x^(2)) - 1(10x) + 1(25))
(x + 9)/(x(x^(2) - 10x + 25) + 1(x^(2) - 10x + 25))
(x + 9)/((x + 1)(x^(2) - 10x + 25))
(x + 9)/((x + 1)(x^(2) - 5x - 5x + 25))
(x + 9)/((x + 1)(x(x) - x(5) - 5(x) + 5(5))
(x + 9)/((x + 1)(x(x - 5) - 5(x -5)))
(x + 9)/((x + 1)(x - 5)(x - 5))
(x + 9)/((x + 1)(x - 5)^(2))
