A(b)=10*((b+7)/2)
A(b)=5(b+7)
b+7=A/5
b=A/5 - 7
B(a) = a/5 - 7
Answer C.
The fraction in the second parentheses is equal to 3,000. That's also (3 x 10^3). You ought to be able to multiply that by the number in the first parentheses.
Answer:
6h^2 -4h -2
Step-by-step explanation:
(h^2 +4h -4) +(5h^2 -8h +2)
= h^2(1 +5) +h(4 -8) +(-4 +2) . . . . group like terms
= 6h^2 -4h -2
Answer:
Find a common denominator on the right side of the equation
Step-by-step explanation:
The equation before the problem is
X² + b/a(x) + (b/2a)²= -c/a + b²/4a²
The next step in solving the above equation is to fibd tge common denominator on the right side of the equation.
X² + b/a(x) + (b/2a)²= -c/a + b²/4a²
X² + b/a(x) + (b/2a)²= -4ac/4a² + b²/4a²
X² + b/a(x) + (b/2a)²=( b²-4ac)/4a²
The right side of the equation now has a common denominator
The next step is to factorize the left side of the equation.
(X+b/2a)²= ( b²-4ac)/4a²
Squaring both sides
X+b/2a= √(b²-4ac)/√4a²
Final equation
X=( -b+√(b²-4ac))/2a
Or
X=( -b-√(b²-4ac))/2a
I believe this is right
Move the decimal over two places so so it becomes .28
Then divide 448 by .28
Which is equaled to 1600
Move the decimal over two places so 24% becomes .24
Then multiply .24 by 1600
And the answer is 384
