Answer:

(3–7x²)(x–3)

Step-by-step explanation:

If you apply the distributive property in (3–7x²)(x–3), you obtain:

3x-9-7x²(x)+21x²

3x-9-7x³+21x²

When you order the expression, you have:

-7x³+21x²+3x-9

Then, the answer is (3–7x²)(x–3)

Answer:

105 cm²

Step-by-step explanation:

The figure is composed of a rectangle and a triangle

area of rectangle = 15 × 6 = 90 cm²

area of triangle = $\frac{1}{2}$ bh ( b is the base and h the height )

Here b = 15 - 9 = 6 and h = 11 - 6 = 5 , thus

area of triangle = $\frac{1}{2}$ × 6 × 5 = 3 × 5 = 15 cm²

Total area = 90 + 15 = 105 cm²

A recipe calls for 2 2/3 teaspoons of salt.you can only find 3 of your measuring spoons:a 1/2 teaspoon,a 1/8 teaspoon,and a 1/6

anyanavicka [17]

U would measure it with the teaspoon and the 1/6 teaspoon
you would need 2 use the 1/2 teaspoon 4 times to get 2 teaspoons and the `1/6 teaspoon 4 times to get 2/3.

1/6+1/6=2/6*2=4/6 =2/3

hope this helps
