Step 1.)

7x + 7 * 4.

We need to expand this term by multiplying a term and an expression.

The following product distributive property will be used:

A(B+C) = AB + AC

Numerical factors in this term have been multiplied.

In our example, the resulting expression will consist of 2 terms:

   the first term is a product of 7 and x

   the second term is a product of 7 and 4.

7x + (7 * 4)

Numerical factors in this term have been multiplied.

Which equals:

7x + 28

Hope you understand this and it helps. Have a great evening!

The value of 5x2 - 11x + 18 is<br> when x = 2.4 and<br> whenx = -3.
Virty [35]

Answer:

20.4

96

Step-by-step explanation:

The value of 5x² - 11x + 18 is

5(2.4)²-11(2.4) +18 = 5(5.76) -26.4+18

= 28.8 -26.4+18 = 20.4 (when x = 2.4)

and 5(-3)² -11(-3) +18 = 45+33+18 = 96

(when x = -3)

exis [7]

Answer: 25%

Step-by-step explanation:

Given: A rectangle has length 4 inches and width 2 inches.

Area = Length x width

= 4 inches x  2 inches

= 8 square inches

If length is reduced by 50% , then length =0.5\times4=2\text{ inches}

If width is reduced by 50% , then length =0.5\times2=1\text{ inch}

Reduced area = (reduced length) x (reduced width)

= 2 inches x 1 inch

= 2 square inches

The percentage of the area of the rectangle be reduced :-

\dfrac{\text{Reduced area}}{\text{Original area}}\times100 \\\\=\dfrac{2}{8}\times100\% \\\\=25\%

Hence, the percent of the area of the rectangle be reduced = 25%
