Answer:
14 x 14 = 196
10 x 14 x 1/2(basically just dividing by 2) = 70
70 x 4(four sides of triangles) = 280
Now let's add the areas together:
196 + 280 = 476 cm^2 is your answer.
Answer:
I suppose that you want to find which gym will be cheaper for you.
We have two equations:
• Gym A: 30m + 50
• Gym B: 10m + 100
First, let's find the value of m such that both gyms cost exactly the same:
30*m + 50 = 10*m + 100
Let's solve this for m
30*m - 10*m = 100 - 50
20*m = 50
m = 50/20 = 2.5
now:
for m < 2.5, Gym A will be cheaper, because the y-intercept is smaller.
for m > 2.5, Gym B will be cheaper, because the slope is smaller,
Then depending on the number of months that Martin wants to go to the gym, he can se the info above to pick the one that is cheaper.

Answer:
x = 8
measure of each side = 27 units
Step-by-step explanation:
Properties of an <u>equilateral triangle</u>:
- Regular polygon with 3 sides
- All 3 sides are <u>equal in length</u>
- All 3 interior angles are congruent
If ΔGHJ is an equilateral triangle, the side measures are equal.
To solve for x, choose 2 side lengths, equate them, and solve for x:
To find the measure of each side, substitute the found value of x into one of the side expressions:
Therefore, x = 8 and the measure of each side is 27 units.
A) 27, 81
b) -30,-15
c) -3, 1
d) -320, 1280
