Answer:
2/-5
Step-by-step explanation:
(-2) - (-4) = 2
(-6) - (-1) = -5
3(5z - 7) + 2(9z - 11) = 4(8z - 7) - 111
15z - 21 + 18z - 22 = 32z - 28 - 111
33z - 43 = 32z - 139
33z - 32z = -139 + 43
z = - 96
5^(x+3)=25^(x-2)
Apply the exponent rule ( 5 ^2 = 25, so remove the 5 and replace 25?with 2)
x + 3 = 2(x-2)
Simplify:
X + 3 = 2x -4
Add 4 to both sides:
X + 7 = 2x
Subtract x from both sides
X = 7
Answer: x = 7
Divide the box into two parts for easy way answer
For cube:-
TSA
Cancel one side area
For triangular pyramid:-
Area of one base
- 0.5(Base)(Height)
- 0.5(12)(15)
- 6(15)
- 90cm^2
Area of four sides=90(4)=360cm^2
<h3>Total surface area:-</h3>
