I would say ummmmmmm probably 31.71
Answer:
perimeter=32t units
Step-by-step explanation:
let:
a=8t-2
b=8t+2
<u>perimeter=2(a+b)</u>
<u>Subtitute values of a and b:</u>
=2(8t-2+8t+2)
=2(16t)
=<u>32t units</u>
Answer:
your answer would be 2
Step-by-step explanation:
Convert 1 3/12 into an improper fraction which is 5/4
Then add it with 9/12
5
/4 + 9
/12
(5 × 12) + (9 × 4)
---------------------------
4 × 12
= 96/48
= 96 ÷ 48
-------------------
48 ÷ 48
= 2
2 is your answer hope this helps :)
Ok, so you want to substitute g and f in these equations so the f(x) = 2x+3x2-5 is equal to 10+6-5 or 11. The other equation is equal to 19. For the explanation put " I found this answer by substituting the given values for the variables in the equation". Your Welcome!
Answer:
∠ b = 12°
Step-by-step explanation:
Complementary angles sum to 90°, thus
a + b = 90 ← substitute a = 78
78 + b = 90 ( subtract 78 from both sides )
b = 12
That is ∠ b = 12°
