Answer:
-12x+20
Step-by-step explanation:
Subtract similar numbers:
2x - 14x = -12x
Product:
12 - 12x + 8
Group the terms that are similar:
-12x + 12 + 8
Add the numbers:
-12x + 20
Final answer:
-12x + 20
Answer:
C. 25
Step-by-step explanation:
sister's cookies = 2.5* boy's cookies
sisters cookies = 2.5 * 10
sister's cookies = 25
Y= 4 is perpendicular to the x- axis
The x- axis is the horizontal line, and the y- axis is the vertical line
Answer:
A =

Step-by-step explanation:
In this question, we are tasked with calculating the area of a triangle given the length of its three sides
Mathematically, we can calculate this using the Heron's formula
For Heron's formula, A = 
WHERE S = 
we take the lengths of the triangle as A,B and C respectively as given
S = (12 + 14 + 18)/2 = 22
Plugging the values into the equation, we have;
A = 
A =

Answer:
8.75%
Step-by-step explanation:
The formula for calculating simple interest (I) is
I = 
where P is the principal, R the rate of interest and T the time in years
here I = 350, P = 2000 and T = 2, hence
350 = ![\frac{2000(2)R[tex] = [tex]\frac{4000R}{100}](https://tex.z-dn.net/?f=%5Cfrac%7B2000%282%29R%5Btex%5D%20%3D%20%5Btex%5D%5Cfrac%7B4000R%7D%7B100%7D)
multiply both sides by 100
35000 = 4000R ( divide both sides by 4000 )
R = 8.75%
