Step-by-step explanation: (3x15)+(5x16)+(2x17)+(2x18)=195
the answer is C or A. I believe
Step 1 :
(23 x 2 - 5) • x 3
Step 2 :
Trying to factor as a Difference of Squares :
Factoring: 8 x 2-5
Theory : A difference of two perfect squares, A2 - B2 can be factored into (A+B) • (A-B)
Proof : (A+B) • (A-B) =
A2 - AB + BA - B2 =
A2 - AB + AB - B2 =
A2 - B2
Answer:
(8 x 2 - 5) • x 3
A) 51, assuming this is a *right* triangle:
38^2+34^2 = 50.99^2, rounding 51!!
