1st problem:
A = 630 cm
2nd problem:
A = 104 cm
All I can see on the picture you provided.
4^4 * 4^(-9) = 4^(4-9) = 4^(-5) or 1/(4^5)
K=8k+28
subtract 8k from both side
-7k = 28
divide both side by -7
k= -4
Answer:
Eight times ten plus six times one plus two times one-tenth plus seven times one-thousandth.
Step-by-step explanation:
(8 x 10) = eight times ten
(6 x 1) = six times one
(2 x 0.1) = two times one-tenth
(7 x 0.001) = seven times one-thousandth
I am not always the best with the equations to words stuff, so please comment if I am wrong!
Hi again! so vertical angles are angles that are across from eachother, so it would be 5 and 7 and 6 and 8
