Answer:

Width = 52 yards

Length = 208 yards

Step-by-step explanation:

(2 * 4x) + 2x = 10x

10x = 520

x = 52

52 * 4 = 208

(208 * 2) + (52 * 2) = 416 + 104 = 520 yards

What is the correct answer?
Svetlanka [38]

Answer:

Terms must have the same variable (letter) and the same exponent (little number)

(7x² +3y+ 5) +(9x²+11y- 2)

Opening bracket

7x²+3y+5+9x²+11y-2

keeping like terms together

7x²+9x²+3y+11y+5-2

Since terms having same variable and exponent can be subtracted, added,divided and multiplied

So

Solving like terms we get

<u>16x²+14y+3</u> which is a correct answer.

Please help! i do not understand
prohojiy [21]

Answer:

90%

Step-by-step explanation:

Complimentary means the same. And adding them together would equal 90. Just as you would divide 90 by 3, each individual angle would be equal to 30.
