Answer:
x = -4y/7 + 51/7
Step-by-step explanation:
First, you add all the numbers without variables and are on the same side.
7x - 4 + 4y + 8 = 55
Then you do the opposite sign (for example the opposite of addition is subtraction) of the two numbers without variables on the left side to add them to the right side(what you do on one side of the equation you must do on the other.
4x - 4 + 4 + 4y + 8 - 8 = 55 + 4 - 8
4x + 4y = 51
Then you get the x by itself by doing the same thing you did with the last step by this time with 4y. Because this has a variable, you don't add it onto the 51, but add as a different number.
4x + 4y - 4y = 51 - 4y
4x = -4y + 51
Now to isolate the x, you divide 4x by 4.
4x/4 = -4y/7 + 51/7
x = -4y/7 + 51/7
Your answer is x = -4y/7 + 51/7
The answer is 54πx² + 144πx + 96π
The surface area of cylinder (SA) is:
SA = 2 π r h + 2 π r²
<span>The height of the gift box is twice the radius: h = 2r
r = 3x + 4
h = 2(3x + 4) = 6x + 8
SA = </span>2 π r h + 2 π r²
SA = 2π (r * h + r²)
SA = 2π ((3x + 4)(6x + 8) + (3x + 4)²)
SA = 2π(18x² + 24x + 24x + 32 + 9x² + 24x + 16)
SA = 2π(27x² + 72x + 48)
SA = 54πx² + 144πx + 96π
5215 sq ft. S= p times h /2 +B
35*4 * 57/ 2. + 35*35
Got h=57 by a2+b2=c2
17.5 sq+ 55 sq =5215 sq rt of 5215 is 57
