Answer:
Let's go part by part:
14 raised to 2 = 196
-9+7x2=-9+14 = 5
196/5= 39,2 (final result)
Solve for x:5 x + 3 (x + 4) = -20
3 (x + 4) = 3 x + 12:3 x + 12 + 5 x = -20
Grouping like terms, 5 x + 3 x + 12 = (5 x + 3 x) + 12:(5 x + 3 x) + 12 = -20
5 x + 3 x = 8 x:8 x + 12 = -20
Subtract 12 from both sides:8 x + (12 - 12) = -12 - 20
12 - 12 = 0:8 x = -20 - 12
-20 - 12 = -32:8 x = -32
Divide both sides of 8 x = -32 by 8:(8 x)/8 = (-32)/8
8/8 = 1:x = (-32)/8
The gcd of -32 and 8 is 8, so (-32)/8 = (8 (-4))/(8×1) = 8/8×-4 = -4:Answer: x = -4
Answer:
The answer to your question is:
61.- 25
62.- 26
Step-by-step explanation:
61.-
2(5x + 5) + 2(2x) = 360
10x + 10 + 4x = 360
14x = 360 - 10
14x = 350
x = 350/14
x = 25
62.-
2(4x - 4) + 2(3x + 2) = 360
8x - 8 + 6x + 4 = 360
14x - 4 = 360
14x = 360 + 4
14x = 364
x = 364 / 14
x = 26
Answer:
each side is 55.125cm
Step-by-step explanation:
you have to divide the area by 2
then do 441/2=220.5
then divide this by 4 because a square has 4 equal sides so 220.5/4=55.125
