A= 1/2(bh)
h=4b
50= (1/2)(b*4b)=2b^2
25=b^2
base = 5 that's your answer
height = 4xb = 4x5=20
Answer:
+3
Step-by-step explanation:
(-m)^(-3) = -m^3, since (-1)^-3 = 1 / (-1).
If m = 2 then we have -2^(-3), or -1 / [2^3]), or -1/8.
Finally, if n = -24, the original expression becomes
(-1/8)(-24) = +3
Second problem: Only the first expression simplifies to a negative result.
Answer:
1) 2a+4a+10-6= 6a + 4
2) 3x-5x+7-7= -2x
3) - 15b+10 +10b= -5b + 10
4) - 4d+d-8-6+3b= - 3d - 14 +3b
To find T, you add 25 to both sides, isolating the varible. This gives you T=-19
Hope this helped!
