2x^2 + 16x + 50 = 0
divide through by 2:-
x^2 + 8x + 25 = 0
(x + 4)^2 - 16 + 25 = 0
(x + 4)^2 = -9
x+4 = 3i or -3i
x = -4 + 3i , -4 - 3i
Answer:
27 Chickens
Step-by-step explanation:
<em>Represent the chicken with A and the cows with B</em>
Given
A has 2 legs and B has 4; So:
Required
Determine A and B
Make B the subject of formula in the first equation
Substitute 30 - A for B in the second equation
Open the bracket
Collect Like Terms
Divide through by -2
<em>Hence, the farmer has 27 chickens</em>
The two numbers are <u>19 and 52.</u>
<h3>
EXPLANATION</h3>
19 x 3 = 57, 57 - 5 = 52, 52 - 19 = 33.
Hope this helps!
The measurements that show equal length is 15 yd and 540 in, 195 ft and 2340 in, 5280 yd and 15840 ft
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
1 ft = 12 in; 1 yd = 3 ft and 1 yd = 36 in.
Hence:
15 yd = 15 yd * 36 in per yd = 540 in
195 ft = 195 ft * 12 in per ft = 2340 in
5280 yd = 5280 yd * 3 ft per yd = 15840 ft
The measurements that show equal length is 15 yd and 540 in, 195 ft and 2340 in, 5280 yd and 15840 ft
