4 times 1 = 4
and 7 times 8 = 56
so 4/56 is your answer. Your teacher prolly wants you to simplify that answer.
Answer:
Step-by-step explanation:
Provef
In the ∆VXW and ∆ZXY given that
WX~= YX, VX~=ZX and the included angleVXW = the included angleZXY (vertically opposite angles are equal to each other)
Therefore
∆VXW ~= ∆ZXY [SAS Theorem]

ANSWER:</h2>
<em>I wonder if you have your equation wrong, because(a−b)2=(a−b)(a−b)=a2−ab−ba+b2=a2–2ab+b2</em>
<em> </em>
<em> Your equation, on the other hand, is (a+b)2 and that is not equal to (a−b)2 except when ab=0, i.e. when either a or b equals 0, and that is not what we normally mean by “prove”. Prove would imply “for all values of a and b”, which is not the case in the form you have your equation,</em>
