Answer:

  (x, y) = (10, 2)

Step-by-step explanation:

The upper angle marked with an expression in x and y is supplementary to the angle marked 70°. The lower angle marked with an expression in x and y is an alternate interior angle with respect to the one marked 70°, is equal to that. This gives the two equations in x and y:

  6x +10y +30 = 110

  4x +10y +10 = 70

Subtracting the second equation from the first gives ...

  2x +20 = 40

  x +10 = 20 . . . . . divide by 2

  x = 10 . . . . . . . . . subtract 10

Substituting into the second equation gives ...

  4(10) +10y +10 = 70

  4 + y + 1 = 7 . . . . . . . . divide by 10

  y = 2 . . . . . . . . . . . . . . subtract 5

The values of x and y are 10 and 2, respectively.

4. Kiran's uncle is 54 years old. He is 8 years older than three times Kiran's age. Find Kiran's age,​

Answers

Kiran's age = x

Uncle's age = 54

Also,

Uncle's age = 8 + 3x

Now,

8 + 3x = 54

3x = 54 - 8

3x = 46

x = 46/3

x = 15.33

The polynomial below is a perfect square trinomial of the form A2 - 2AB + B2.

9x^2-36x+16

A.True
B.False​

Answers

Step-by-step explanation:

9x² - 36x + 16

= (Ax - B)² = A²x² - 2ABx + B².

By Comparing Coefficients, we have:

A² = 9,

2AB = 36,

B² = 16.

It is obvious that A = 3 and B = 4.

However 2AB = 2(3)(4) = 24 which is not equal to 36.

Hence 9x² - 36x + 16 is not a perfect square trinomial.

Answer:

False

Step-by-step explanation:

The polynomial cannot be factored.

y=6x−7. Identify the x-intercept.

Answers

Answer: x = 7/6

Step-by-step explanation:

X intercept is when y = 0.

Set y = 0

0 = 6x - 7

Add 7 to both sides

7 = 6x

Divide by 6

x = 7/6

Answer:

x = 7/6

Step-by-step explanation:

When finding the x-intercept using slope intercept form. Substitute 0 for y and solve for x.

0 = 6x - 7

~Add 7 to both sides

7 = 6x

~Divide 6 to both sides

7/6 = x

Answer:

Area of figure is 51 cm²

Step-by-step explanation:

We need to find the area of the figure given.

The figure is basically a combination of 3 rectangles.

Adding area of all the rectangles will give the area of the figure.

The formula used is: [tex]Area\:of\:rectangle=Length\times Width[/tex]

Area of rectangle 1:

Length = 7 cm

Width = 3 cm

The area will be:

[tex]Area\:of\:rectangle=Length\times Width\\Area\:of\:rectangle=7\times 3\\Area\:of\:rectangle=21 \:cm^2[/tex]

The area of rectangle 1 is 21 cm²

Area of rectangle 2

Length will be: 7-4 = 3cm

Width will be: 3 cm

The area will be:

[tex]Area\:of\:rectangle=Length\times Width\\Area\:of\:rectangle=3\times 3\\Area\:of\:rectangle=9 \:cm^2[/tex]

The area of rectangle 2 is 9 cm²

Area of rectangle 3

Length will be: 7cm

Width will be: 3 cm

The area will be:

[tex]Area\:of\:rectangle=Length\times Width\\Area\:of\:rectangle=7\times 3\\Area\:of\:rectangle=21 \:cm^2[/tex]

The area of rectangle 3 is 21 cm²

The total area of the figure will be:

Area of figure = Area of rectangle 1 + Area of rectangle 2 + Area of rectangle 3

Area of figure = 21+9+21

Area of figure = 51 cm²

So, Area of figure is 51 cm²

find the area of the unshaded reason for these two problems​

Answers

9514 1404 393

Answer:

  a) 96 m²

  b) 26,000 ft²

Step-by-step explanation:

The area of the unshaded region is the difference between the overall area of the rectangle and the area of the shaded region. It can also be found directly using the dimensions of the unshaded region.

a) We have the height of the right triangle, but need to know its base. The Pythagorean theorem can help with that. Let the base of the triangle be represented by x. Then ...

  x² +16² = 20²

  x² = 400 -256 = 144

  x = √144 = 12

The area of the unshaded triangle is given by the formula ...

  A = (1/2)bh

  A = (1/2)(12)(16) = 96 . . . . square meters

__

b) The shaded area at upper left is a square 100 ft on a side. Its area is ...

  A = s² = (100 ft)² = 10,000 ft²

The shaded area at upper right is a triangle with base and height 120 ft and 150 ft. Its area is ...

  A = (1/2)bh = (1/2)(120 ft)(150 ft) = 9,000 ft²

The area of the overall rectangle is ...

  A = LW = (300 ft)(150 ft) = 45,000 ft²

So, the unshaded area is ...

  unshaded area = overall area - left shaded area - right shaded area

  unshaded area = 45,000 ft² -10,000 ft² -9,000 ft² = 26,000 ft²
