Answer:
12 cm
Step-by-step explanation:
Well first we can cut the triangle in half and use the Pythagorean theorm
a^2+b^2=c^2
In this case we are going to be doing c^2-a^2=b^2
10^2-8^2=b^2
(10*10)-(8*8)=b^2
100-64=b^2
36=b^2
Now we just square root 36 (what number times itself is 36)
b=6
Since half of the one side equals 6 (DC) then the length of AC is 12!
10,000 because 5 and higher Go up 4 and lower go down
4b + 22 = 5 (b + 4) - 1 (remove the parantheses)
4b + 22 = 5b + 20 - 1 (calculate)
4b + 22 = 5b + 19 (move the terms)
4b - 5b = 19 - 22 (collect like terms and calculate)
-b = -3 (change the signs)
<em>b = 3</em>
Answer:
x = 1/4
Step-by-step explanation:
in order to evaluate for the value of x in the equation 5( 4x + 2) + 10 = 25
we are going to open the bracket the combine the like terms together and evaluate.
solution
5 (4x + 2) + 10 = 25
20x + 10 + 10 = 25
combine the like terms
20x = 25 - 10 -10
20x = 5
divide both sides by the coefficient of x
20x/20 = 5/20
x = 1/4
therefore the value of x in the expression 5 4x + 2) + 10 = 25 is evaluated to be 1/4
