It’s really simple you can just type the equation into the calculator but it’s basically 8^3 which is 8 x 8 x 8 which is 512 and divide that by 2 which is 256 and add 9 which is 265.

Step-by-step explanation:

$9 + \frac{ {8}^{3} }{2} \\ 9 + \frac{8 \times 8 \times 8}{2} \\ 9 + \frac{512}{2} \\ 9 + 256 \\ 265$

What is the value of B - A as a fraction?

umka21 [38]

Answer:
A = 1/4
B = 3/4

step-by-step explanation:
the middle should be 1/2 because the middle between 0 and 1 is 1/2
A and B are both in the middle of the sides
therefore A would be closer to 0 so 1/4
and B would be closer to 1 so 3/4

The larger leg of a right triangle is 3cm longer than its smaller leg. The hypotenuse is 6cm longer than the smaller leg. how ma

Natalka [10]

$b=a+3\\
c=a+6\\
a^2+b^2=c^2\\\\
a^2+(a+3)^2=(a+6)^2\\
a^2+a^2+6a+9=a^2+12a+36\\
a^2-6a-27=0\\
a^2-9a+3a-27=0\\
a(a-9)+3(a-9)=0\\
(a+3)(a-9)=0\\
a=-3 \vee a=9\\
$

The length can't be negative, so the answer is 9 cm.
