Use the diagram and the Pythagorean Theorem to find the EXACT area of square ABCD

Burka [1]

ANSWER

The area of square ABCD is
$25 \: square \: unit$

EXPLANATION

The area of square ABCD is the square of the length of one side.

That is the area of ABCD is |AD|²

From Pythagoras theorem,

${|AD|}^{2} = { |AG| }^{2} + { |GD| }^{2}$

We can read from the graph that, each box is one unit.

This implies that,

${|AD|}^{2} = {4}^{2} + {3}^{2}$

${|AD|}^{2} =16 + 9$

${|AD|}^{2} =25$

Therefore the area of square ABCD is 25 square units.

The correct answer is option C.

Answer:

y = 20
4^8
x = 0

Step-by-step explanation:

The applicable rules of exponents are ...

(a^b)(a^c) = a^(b+c)

a^0 = 1 . . . . for a ≠ 0

And, it is convenient to know the cubes of small integers:

1³ = 1; 2³ = 8; 3³ = 27; 4³ = 64; 5³ = 125

6³ = 216; 7³ = 343; 8³ = 512; 9³ = 729; 10³ = 1000

1) p^3 × p^5 = p^-12 × p^y

Equating exponents:

3 + 5 = -12 + y

20 = y . . . . . . . . . . . add 12

2) 64 × 4^5 = 4^3 × 4^5 = 4^(3+5) = 4^8

3) 10^x = 1 = 10^0

x = 0
