Answer:
1/5
Step-by-step explanation:
It is easy to see a right triangle on each side of the original square with its hypotenuse on the side of the original square, each with an area of 2⋅A2=A. Thus the total area of the original square is 5A, or the ratio of the area of the shaded square to the original square is 1/5.
Answer:
24:18
Step-by-step explanation:
Let x be the constant of proportionality...
Hence,
4x+3x=42
7x=42
x=6
Hence,
24:18 is your answer
Answer:
x intercept = -3
x intercept = 1
x intercept = 2
Step-by-step explanation:
The x-intercepts are where the graph crosses the x-axis
Value of x when y = 0
crosses the x-axis at (negative 3, 0), (1, 0), and (2, 0),
x intercept = -3
x intercept = 1
x intercept = 2
x y
-3 0
-1.5 13
0 6
1 0
1.5 -1
2 0
pls mark me the brainliest pls i have been waiting to be the braintiest for 5 years pls mark me the brainliest
7c² + 8c + 1 = 0
c = <u>-(8) +/- √((8)² - 4(7)(1))</u>
2(7)
c = <u>-8 +/- √(64 - 28)</u>
14
c = <u>-8 +/- √(36)
</u> 14
c = <u>-8 +/- 6</u>
14
c = <u>-8 + 6</u> c = <u>-8 - 6</u>
14 14
c = <u>2</u> c = <u>-14</u>
14 14
c = ¹/₇ c = 1
The solution is equal to { 1, ¹/₇}.
