Area of the given shape = Area( Triangle + Square + Rectangle)

Area of Triangle = 1/2 x base x height

= 1/2 x (7-2) x (9-5)

= 1/2 x 5 x 4

= 10

Area of square = side × side

= (7-2) x ( 9-4)

= 5 x 5

= 25

Area of rectangle= base x height

= 2 x 5

= 10

Therefore , the area of given shape = 10+25+10 = 45

What is the following simplified product? Assume

Yanka [14]

Answer:

The correct answer option is D. $10x^4\sqrt{6}+x^3\sqrt{30x}-10x^4\sqrt{3}-x^3\sqrt{15x}$ .

Step-by-step explanation:

We are given the following expression:

$\left ( \sqrt { 10 x ^ 4 } -x \sqrt { 5 x ^ 2 } \right ) \left ( 2 \sqrt { 15 x ^ 4 } + \sqrt { 3 x ^ 3 } \right )$

Assuming that $x\geq 0$ , we are to find its simplified product.

$\left ( \sqrt { 10 x ^ 4 } -x \sqrt { 5 x ^ 2 } \right ) \left ( 2 \sqrt { 15 x ^ 4 } + \sqrt { 3 x ^ 3 } \right )$

$\\\\ = 2 \sqrt { 150 x ^ 8 } + \sqrt { 3 0 x ^ 7 }-2x\sqrt{75x^6}-x\sqrt{15x^5} \\\\ =2\sqrt{25\times6x^8}+x^3\sqrt{30x}-2x\sqrt{25\times3x^6}-x^3\sqrt{15x} \\\\ =10x^4\sqrt{6}+x^3\sqrt{30x}-10x^4\sqrt{3}-x^3\sqrt{15x}$

a barn casts a shadow that is 12 meters long while a tree in the yard casts a shadow that is 8 meters long. how long is the tree

STALIN [3.7K]

Using proportion...

length of barn length of tree
-------------------------------- = --------------------------------
length of barn's shadow length of tree's shadow

20 x
---- = ---
12 8

Using cross-multiplication...

20 x 8 = 12x
160 = 12x
x = 13 1/3 or 13.3333

The tree is 13 1/3 meters long.

If f(x) = 3x2 - 2x + 5, find f(-2) A) -27 B) -11 C) -3 D) 21

Digiron [165]

Answer:

Step-by-step explanation:

You have to be careful that you treat 21 as special. It is the only positive number. As you do the problem, keep an eye on 21.

f(-2) = 3x^2 - 2x + 5 Put -2 wherever you see an x

f(-2) = 3(-2)^2 - 2(-2) + 5 Calculate the first term.

f(-2) = 3(4) - 2(-2) + 5 Remove the brackets of the second term

f(-2) = 12 + 4 + 5 Combine

f(-2) = 21
