Answer:
$1.21 he will recieve
Step-by-step explanation:
Answer:
<h3>162.5 cm²</h3><h3>
Step-by-step explanation:</h3>
Area of a triangle = (BH)/2
Base= 25
Height=13
(25×13)/2= 162.5 cm²
The main property is as follow
(A^p)^q=A^pxq
so only Sam's work is correct because
(8^4)^5 x(7^3)^9=(8^4x5)x(7^3x9)=8^20x 7^27
Answer:
The two roots of the quadratic equation are
Step-by-step explanation:
Original quadratic equation is
Divide both sides by 9:
Add to both sides to get rid of the constant on the LHS
==>
Add to both sides
This simplifies to
Noting that (a + b)² = a² + 2ab + b²
If we set a = x and b = we can see that
=
So
Taking square roots on both sides
So the two roots or solutions of the equation are
and
So the two roots are
and
The answer is bc/2a^2, just simplify the expression
