answer choice a

x^2 - 5x - 1 = 0

a=1, b=-5, and c=-1

next you plug in the numbers into the quadratic formula

-(-5) plus or minus the square root of (-5)^2 - 4(1)(-1)/ 2(1)

after you simply, you should get 5 plus or minus the square root of 29, which is answer choice a

Easy question, easy points
Juli2301 [7.4K]

Answer:

Step-by-step explanation:

The solution of a system of linear equations is the point of intersection of their graphs because the intersection represents the only x or y values that will satisfy both/all equations. The graph visually shows that the intersection of these equations is the only spot on the graph that all of the equations have in common. This means that only this spot will satisfy all equations. For example, the intersection may be (0,1); this means that for all equations an x value of 0 will always result in the y value of 1. However, an x or y value that satisfies one equation may not satisfy the others if they do not lead to the desired outcome.

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}
