First multiply everything inside the brackets by seven
7x^4-42+3
Then solve what you can
7x^4-39
You an't solve it further. Is this what you mean? X to the fourth power?
First set up the equation based on the description.
x + 16 = 3x
Use subtraction to get the "x"s on one side of the equation. You can next subtract <span>
x from both sides.
16 = </span>
<span> x
Now you can multiply both sides of the equation by </span>
<span> to solve for x
x = 6</span>
Anna picked 6 apples
Sabrina picked 7 <em>times</em> as many apples.
Multiply the two numbers together
6 x 7 = 42
Sabrina picked 42 apples

So hmm check the picture below
the radius "r" is half the diameter, meaning, the diameter is 2r long
now, if the height "h" is twice "d" or 2d, then that means h = 2(2r)
thus
