Answer:
2. 4
Step-by-step explanation:
use the formula A=ab/2
a-leg 1
b-leg 2 (base)
since it is a right triangle the height would be 2 cm and the base would be the leg (4 cm)
plus into the equation- A= 2(4)/2
8/2=4
Answer:-24
Step-by-step explanation:
You multiply your numbers without the - or the +
You check ehich number is bigger and you use it symbol for the answer
Example: 3x8= 24
-8 is bigger than 3 so you use it symbol
= -24
R(s + t) = st
Rs + Rt = st
Rs - st = -Rt
s ( R - t) = -Rt
*s = - Rt / (R - t) Multiply through by -1 on the right.
*s = Rt / (t - R) Put in the brackets in your answer. What you have been writing means
s = Rt/r - R you need the brackets. The stars mean that either could be an answer. I think your problem could be the brackets. Now I'm reasonably certain this is correct.
