Answer: 49 cm² and 16 cm²
Step-by-step explanation:
1. If the triangles are similar and the ratio of the perimeter os 4:7, then the areas are in the following ratio:
2. You know that the sum of their areas is 65 cm², then, you can calculate the area of the larger triangle as following:
3. The area of the smaller triangle is:
To evaluate this expression properly, we must follow order of operations (PEMDAS) rules. Here, that means doing exponentiation first, followed by mult. and div., followed by addition and subtraction.
2−4÷2+2^3 becomes 2−4÷2+8 after exponentiation.
2−4÷2+8 becomes 2-2+8 after division.
2-2+8 = 8
Your final value for this expression is 8.
Answer:
it’s -93
Step-by-step explanation:
The slope would be 1/4x :)
First, start with the basic line equation:
y = mx + b
Then, fill in what you know.
-4 = 2(3) + b
Solve for b
-4 = 6 + b
-6 -6
-10 = b
Now you have your equation:
y = 2x - 10
I hope this helps :)
