20 x 20 = 400
4(1/2 x 20 x 30) = 1200
400 + 1200 = 1600
So, D
For this case we must solve the following inequality, finding the values for the variable "t":

We subtract 18 from both sides of the inequality:

Thus, the variable "t" is defined for all strict lower values than 25.
Answer:

Option A
Answer:
True
Step-by-step explanation:
Answer:
-22
Step-by-step explanation:
Let the unknown be x,
Step 1: You first write the question in equation form,
2(x-8)=3(x+2)
Step 2: You clear the brackets by multiplying the number outside with the numbers inside the bracket,
2x-16=3x+6
Step 3: Collect like terms,
2x-3x=6+16
Step 4;Solve
2x-3x=6+16
-x=22
<em>Therefore </em><em>x=</em><em>-</em><em>2</em><em>2</em>
