Answer:
Short answer: D) 15
Step-by-step explanation:
Parallel lines in this kind of triangle are always in a strict ratio of small to large or large to small based on how you look at it.
So we have 4cm to 6cm, which is 2:3 ratio. We know the smaller side, but want the larger side, so we can set up 2/3 = 10/?
the ? is 15.
Answer:
(a) f(7) = 23
(b) x = 13/3
Step-by-step explanation:
Step 1: Define
f(x) = 3x + 2
(a) f(7) is x = 7
(b) f(x) = 15
Step 2: Substitute and Evaluate
(a) f(7) = 3(7) + 2
f(7) = 21 + 2
f(7) = 23
(b) 15 = 3x + 2
13 = 3x
x = 13/3
Answer:
Step-by-step explanation:
After selecting A there are 6 letters that are not K out of the remaining 7 letters so
P(!K)=6/7
Mathematical processes are the steps used to determine the result of operations
- The perimeter of the rectangle is

- The area of the rectangle is

The dimension of the rectangle is given as:


<u>(1) The perimeter of the triangle</u>
This is the sum of the side lengths of the rectangle.
So, we have:

This gives

Collect like terms

Open brackets

Hence, the perimeter of the rectangle is 
<u>(2) The area of the triangle</u>
This is the product of the dimensions of the rectangle.
So, we have:

This gives

Open brackets

Collect like terms


Hence, the area of the rectangle is
