Well, the formula is: A= [(b1+b2)/2]h
So first we have to add 8.52 and 22.2, which is 30.72. Now, divide this by two, which would give us 15.36. Then, you multiply the height, which is 9.86. This will give us the answer of 151.4496 cm squared.
Hope this helps!

Formulas:
A= (b1+b2) /2 X h

A= (22.2+8.52) x 9.86
A=30.72x9.86
A= 302.90

All you have to do is go in the order of operations, and your answer is simple:
<span>6² / (6+3) + 18 / 3 - 3²
= 36 / (9) + 6 - 9
= 4 + 3
= 1</span>

Anyone help me. ....

Answer:

Step-by-step explanation:

Using the rules of exponents

All the exponents inside the parenthesis are multiplied by the exponent outside the parenthesis.

Then

$\frac{m^{-7}n^{14} }{m^{-25}n^{40} }$ ÷ $\frac{m^{-21}n^{42} }{m^{-25}n^{40} }$

[ Using the rule $\frac{a^{m} }{a^{n} }$ = $a^{(m-n)}$ ]

= $m^{(-7-14)}$ $n^{(14-(-28)}$ ÷ $m^{(-15-10)}$ $n^{(25-(-15)}$

= $m^{-21}$ $n^{14+28}$ ÷ $m^{-25}$ $n^{25+15}$

= $\frac{m^{-21}n^{42} }{m^{-25}n^{40} }$

= $m^{(-21-(-25))}$ $n^{(42-40)}$

= $m^{(-21+25)}$ n²

= $m^{4}$ n² = $m^{x}$ $n^{y}$ , so x = 4 and y = 2

Then

$m^{x-2y}$ = $m^{4-2(2)}$ = $m^{4-4}$ = $m^{0}$ = 1 ← as required

Solve - ( c - 3) = 6

vladimir1956 [14]

Distribute the negative outside the parenthesis through the terms inside the parenthesis.

-c + 3 = 6

Subtract 3 from both sides.

-c = 3

Divide both sides by -1.

c = -3
