The ratio of the perimeters of two similar triangles is 4:7. What is the area of each of these triangles if the sum of their are
attashe74 [19]

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:

4^{2}:7^{2}\\16:49

2. You know that the sum of their areas is 65 cm², then, you can calculate the area of the larger triangle as following:

A_1=65(\frac{49}{49+16})=49cm^{2}

3. The area of the smaller triangle is:

A_2=65(\frac{16}{49+16})=16cm^{2}

HURRY!!!<br> Simplify. 2−4÷2+2^3 <br><br> −5 <br> 2 <br> 7 <br> 8
ivanzaharov [21]

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.

Write the equation of a line that has a slope of 2 and goes through (3,-4).
kati45 [8]
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 :)
