Answer:

3 metres

Step-by-step explanation:

Let the width of the pathway be x

Area: (9+2x)(4+2x)

36 + 8x + 18x + 4x²

4x² + 26x + 36

Increased area is 150:

4x² + 26x + 36 = 150

4x² + 26x - 114 = 0

2x² + 13x - 57 = 0

2x² + 19x - 6x - 57 = 0

x(2x + 19) - 3(2x + 19) = 0

(x - 3)(2x + 19) = 0

x = 3, x = -19/2

the interor angles of a triangle have measures 100 degrees 4y+25 degrees and 3y+20 degrees whats the value of y ​
pav-90 [236]

Answer:

y = 5

Step-by-step explanation:

The 3 interior angles of a triangle sum to 180°

Sum the 3 given angles and equate to 180

100 + 4y + 25 + 3y + 20 = 180 ← simplify left side

7y + 145 = 180 ( subtract 145 from both sides )

7y = 35 ( divide both sides by 7 )

y = 5

The length of a rectangle is 4 cm greater than the width of the rectangle.
Sunny_sXe [5.5K]
Answer: a) 9 cm

explanation: since the length of the rectangle is 4 cm greater than the width, you can just take 9 cm (the length) minus 4, which gets you 5 cm. if we use the area formula (length x width), then 9 x 5 = 45 square cm.

What what is is tan B?
timofeeve [1]

Answer:

Tan B= 16/30

Step-by-step explanation:

Remember SOH CAH TOA. Tan is involved with this problem so we would use the TOA. TOA stands for: T-Tan, O- Opposite, and A- Adjacent.

First you want to find what is the opposite side of angle B (in meaning the side if you go straight out from the angle) which would be 16. You then need to find the adjacent side which is the side in between the given angle and 90 degree angle so that would be 30. TOA states that Opposite is over Adjacent so it would be 16/30.
