Answer:
Step-by-step explanation:
The shape can be divided into two parts, let use the division in the question
So we have two rectangles
The area of a rectangle is given by l×b.
Let the big rectangle be 1
And the smaller rectangle be 2
Rectangle 1
Length is 16cm, breadth is 6cm
Area=l ×b
Area=16×6
Area=96cm^2
Rectangle two
The length will be 14-6=8cm
And the breadth will be 16-2=14cm
Then,
Area=l ×b
Area=14×8
Area=112cm^2
Total area is
Area1+Area2
112+96
Total area=208cm^2.
Answer:
Hence x = -1 and y = 18
<em></em>
Step-by-step explanation:
Given the system of equations
y + 8x = 10... 1
2y - 4x = 40 ... 2
From 1; y = 10-8x
Substitute into 2;
2(10-8x) - 4x = 40
20 - 16x - 4x = 40
20 - 20x = 40
-20x = 40 - 20
-20x = 20
x = -1
Recall that y = 10-8x
y = 10 - 8(-1)
y = 10 + 8
y = 18
Hence x = -1 and y = 18

Answer:
Rational because it isn't a repeating decimal
Step-by-step explanation:
Answer:
i tried it by trial and error, and my work is below.
Step-by-step explanation:
2x + 9 = 23
subtract 9 from both sides
2x = 14
guess.... lol
x=7
By the table, it seems to be that f = 1/2x
