Can anyone plz solve this ?? -7 (1+3x) =4+5x
Aleonysh [2.5K]

Step-by-step explanation:

-7(1+3x) = 4 + 5x

-7 - 21x = 4 + 5x

(get all the variables on one side. Don't forget to change the signs)

-7-4 = 5x + 21x

-11 = 26x

(divide both sides by the coefficient [26])

26x/26= -11/26

x = -11/26

Area of triangle height 10 feet<br> Base 4x squared + 2xy squared feet
Brums [2.3K]

Answer:

Since the formula is (1/2) base height, (1/2) of 10 is 5 so multiply 5 times the base polynomial resulting in 20x^2y + 10xy^2 ft^2. So, if you multiply the length times width then divide by 2 you get the same answer. Sorry if this is incorrect.

Hope this helps, have a great day and stay safe!
