Answer:

The length of one plot is 45m & the other length is 25m

Step-by-step explanation:

Let length one sq. plot = x length other sq. plot = y

area of square = length²

x² + y² = 2650 -----(1)

x² - y² = 1400 ------(2)

(1)+(2)

2x² = 4050

x² = 2025

x = 45

subx²=2025into(1)

2025 + y² = 2650

y² = 625

y = 25

-7–5(3g+8)&lt;10g–7+g <br><br> help me please!
Ede4ka [16]

Answer:

-20/13 <g

Step-by-step explanation:

-7–5(3g+8)<10g–7+g

Distribute

-7–15g-40<10g–7+g

Combine like terms

-15g - 47 < 11g -7

Add 15 g to each side

-15g+15g -47< 11g+15g -7

-47 < 26g -7

Add 7 to each side

-47+7 < 26g-7+7

-40 < 26g

Divide each side by 26

-40/26 <26g/26

-40/26 <g

Divide top and bottom by 2

-20/13 <g

If QRST below is a rectangle, find x if angle S is equal to 7x + 55.
bazaltina [42]
Because QRST is a rectangle, that means all of the angles must be a right angle, which are 90 degrees. Using this information, solve the expression by creating an equation that lets angle S = 90.

90 = 7x + 55
35 = 7x
x = 5
