Complete the following statement: The equation is (false, true) when x = 4, so 4 (is, is not) a solution.

Answers

Answer:

False, is not

Step-by-step explanation:

If we plug in 4 for x in the equation, we get that 5 * 4 + 3 = 12, and we can calculate that 20 + 3 = 12, which is not true. 4 is a false solution for that equation so it is not a solution (We can use this info to say that the answer is false, is not).

Answers

208 in^2

find the area of each of the parts (4 triangles and 1 square)

all of the triangles have the same area since this is a square pyramid
area of triangle = (base X height)/2
so it would be (8 X 9)/2 = 36

for the square, the area is length X width
so it would be 8 X 8 = 64

add all the areas
36+36+36+36+64 = 208

Answers

Answer:

1/12

Step-by-step explanation:

When you add or subtract fractions, you need a common denominator.

Let's use the least common denominator of 12, 6, and 3.

Since 12 is a multiple of 6 and 3, the LCD is 12.

7/12 - 1/6 - 1/3 = 7/12 - 2/12 - 4/12 = 5/12 - 4/12 = 1/12

Answer:

1/12
