Answer: an expression obtained by a finite number of the fundamental operations of algebra upon symbols representing numbers.
Step-by-step explanation: In mathematics, an algebraic expression is an expression built up from integer constants, variables, and the algebraic operations. For example, 3x² − 2xy + c is an algebraic expression.
Use the pythagorean theorem A²+B²=C²
Use 21ft for A
Use 14ft for B
Then solve for C (the diagonal)
21²+14²=C²
441+196=C²
673=C²
√<u />673 = √C²
C≈25.24 or if you leave in radical form it is the square root of 637
Answer:
Answer is B ( 314.9 m2)
Step-by-step explanation:
A= H(B)/2
A= 25.6(24.6)/2
A= 314.88
