The first one is the correct answer, just finished it
Answer:
10 x 15 = 150
Area of trapezoid:
10 + 20 = 30
30 x 5 = 150
20 - 15 = 5
150 divided by 2 ( x 1/2) = 75
75 + 150 = 225 square cm
Formula of a trapezoid:
B1(base1) + B2(base2) x H (Height) x 1/2 (basically dividing by 2)
So that ya that cool pog moment I need to answer a question so I can ask a question
√x+3 = 2
First we should simplify the equation by squaring both sides:
x + 3 = 4
Isolate x by taking 3 off both sides:
x = 1
We should ALWAYS check that our answer is correct after working out the value of x. We can do this by substituting x into the original equation:
√x + 3 = 2
Turns into:
√1 + 3 = 2
Which turns into:
√4 = 2
Which is true, therefore we can confirm:
x = 1
