Answer:
Step-by-step explanation:
<u>Approach 1 (trickier)</u>
<u>Approach 2 (easier)</u>
First, distribute the negative seven to the p and negative five in the parentheses. it should look like 36 - 7p = -7p + 35.
Next, add seven p to both sides and it cancels out. 36 -7p = -7p + 35.
+7p= +7p
Then minus thirty five on both sides. You get an inconclusive answer of 1=0
Area of a regular polygon
A = (1/2)ap
a = apothem p = perimeter
in this case we know both, so the area of the square is just
.
The test contains 10 three-point questions and 14 five-point questions.
Step-by-step explanation:
Given equations are;
x + y = 24 Eqn 1
3x + 5y = 100 Eqn 2
Multiplying Eqn 1 by 3;
Subtracting Eqn 3 from Eqn 2;
Dividing both sides by 2;
Putting in Eqn 1,
