Answer:

First find the area of the square

(s x s)

10x10

=100

And then for the triangles

(1/2bh)

1/2 x 10 x 12

=60

since there are 4 triangles of the same area we will multiply 4 with the first triangle's area

60 x 4

=240

Total S.A= 240 + 100

=340 Square Inches

Option B

Hope it helps!

pogonyaev

Answer:

- $\frac{1}{2}$

Step-by-step explanation:

Find slope using the slope formula : $\frac{y2-y1}{x2-x1}$

Plug in the given points : $\frac{4- (-8)}{-11-13}$

Add the numbers : $\frac{12}{-11-13}$

Calculate the difference : $\frac{12}{-24}$

Reduce the fraction : - $\frac{1}{2}$

How to solve 2x-4(x+3)= x-3

Murrr4er [49]

Answer: x=-3

Step-by-step explanation:

2x-4(x+3)=x-3

2x-4x-12=x-3

-2x-12=x-3. add 12 to both sides

-2x=x+9. subtract x from both sides

-3x=9. Divide both sides by -3

x=-3

In a two-digit number, the units digit is 5 more than the tens digit. The number is 6 less than 4 times the sum of the digits. F

KonstantinChe [14]

Answer:

Tens digit, x = 3

Unit digit, y = 8

Number = 38

Step-by-step explanation:

Let the 2 digit number = xy

y = x + 5 - - - (1)

10x + y = 4(x + y) - 6

10x + x + 5 = 4(x + x + 5) - 6

11x + 5 = 4(2x + 5) - 6

11x + 5 = 8x + 20 - 6

11x + 5 = 8x + 14

11x - 8x = 14 - 5

3x = 9

x = 9/3

x = 3

From (1)

y = x + 5

y = 3 + 5

y = 8
