Step-by-step explanation:

Here's an easy way to fold any rectangle of paper into a triangle with three sides the same length.

Fold the paper in half long-ways, then open it out flat.

Fold a bottom corner up to touch the fold line, making a sharp point on the other corner.

Now fold the two RED edges together.

Find three consecutive odd numbers the product of which is 148 more than the cube of their middle number.

Anna11 [10]

Answer:

The numbers are $-39,-37,-35$

Step-by-step explanation:

Let

x-----> the first odd number

x+2----> the middle odd number

x+4---> the third odd number

$x(x+2)(x+4)=(x+2)^{3} +148$

$(x^{2}+2x)(x+4)=(x^{2}+4x+4)(x+2)+148\\x^{3}+4x^{2}+2x^{2}+8x=x^{3}+2x^{2}+4x^{2}+8x+4x+8+148\\x^{3}+6x^{2}+8x=x^{3}+6x^{2}+12x+156\\8x=12x+156\\4x=-156\\x=-39$

The numbers are

$x=-39$

$x+2=-39+2=-37$

$x+4=-39+4=-35$

The product of 7 and a number is greater than 42. If the number is a whole number less than 10 , what could the number be?

julsineya [31]

Answer:

8 or 9

Step-by-step explanation:

Your primary equation that they gave you is ?b and has to be greater than ?a 7 x ?a =42

So your answer to ?a is 7 because 7 x 7 =42 therefore your answer to ?b has to be 8 or above.

the next part of your problem states that it is a whole number UNDER 10.... this limits your possible answer to either 8 or 9.
