SA=2(LW+LH+WH)
if all are trippled then
SA=2(3L3W+3L3H+3W3H)
SA=2(9LW+9LH+9WH)
SA=2(9)(LW+WH+WH)
SA=9(2(LW+WH+WH))
the SA will be multiplied by 9
150 times 9=1350
new surface area is$1350 <span>cm²</span>
The answers are:
B; (225)(0.15) and E; 225 - [(225)(0.85)] Hope this helps!
Answer:
step 6 has an algebraic error
Answer: " m∠SRW = 95 ° " .
________________________________________________
Since m∠TRV = 95° ;
and: ∠TRV and ∠SRW are vertical angles;
and: we are given: " m∠TRV = 95° " ;
and: vertical angles are congruent;
So, m∠TRV = m∠SRW = 95° .
