Answer:
3 1/3
Step-by-step explanation:
x=10/3
Steps to solve:
-k^2 - (3k - 6n) + 2n; k = -3, n = -5
~Substitute ans simplify
-(-3)^2 - (3(-3) - 6(-5)) + 2(-5)
3^2 - (-9 + 30) - 10
~Use PEMDAS and solve the rest
9 - 21 - 10
-13 - 10
-23
Best of Luck!
Answer:
Step-by-step explanation:
Factor out 20 from the expression.
Take 20 as common.
To solve this problem you must apply the proccedure shown below:
1. You have that the formula for calculate the area of a triangle is:
A=bh/2
Where A is the area of the triangle, b is the base of the triangle and h is the height of the triangle.
bh/2=124
bh=124x2
bh=248
2. The problem asks for the new area of the triangle <span>if its base was half as long and its height was three times as long. Then, you have:
Base=b/2
Height=3h
3. Therefore, when you substitute this into the formula for calculate the area of a triangle, you obtain:
A'=bh/2
(A' is the new area)
A'=(b/2)(3)/2
A'=3bh/4
4. When you substitute bh=248 into </span>A'=3bh/4, you obtain:
<span>
A'=186 units</span>²
<span>
The answer is: </span>186 units²
