Answer:
d) 7(30 + 9) = 7(30) + 7(9)
Step-by-step explanation:
<u>Distributive method</u>:
<u>Here given</u>:
Among the option's:
<u>1st option</u> (7 + 3) (7 + 9) is wrong, changes <u>final answer</u>.
<u>2nd option</u> (7 × 30) + 9 is wrong, changes <u>final answer</u>.
3rd option 39 × 7 shows commutative property of multiplication.
<u>4th option</u> show distributive method.
Answer:
$13087.92
Step-by-step explanation:
formula: ab^x
a= starting amount
a= 5072
b= 1+r
r=rate
r=9%=0.09
b=1+0.09 =1.09
x= 11 (years)
account after 11 years:
= 5072(1.09)^11
=13087.9227277
= 13087.92
Lets compare both equations so we can explain the reason for it, and see it clearly:
<span>y1 = 5x + 1
</span><span>y2 = 4x + 2
y1 > y2
</span>5x + 1 > 4x + <span>2
</span>To see why that happens we need to solve for x:
5x - 4x > 2 - 1
x > 1
Therefore, the first equation is greater than the second for values of x > 1
Answer:
The Pythagorean Theorem states: In any right triangle, the area of the square whose side is the hypotenuse (the side opposite the right angle) is equal to the sum of the areas of the squares whose sides are the two legs (the two sides that meet at a right angle).
The Pythagorean theorem can be written as an equation relating the lengths of the sides a, b and c, often called the Pythagorean equation:
a2 + b2 = c2
