The picture is upside down my dude, delete the question, re-upload it and ill help you out.
Answer:
-40
Step-by-step explanation:
Try rearranging and factoring -8y-2c-2b-8x-2a:
This is equal to -8(x + y) -2(a + b + c).
Since x + y = 7, we have:
-8(7) -2(a + b + c)
and since a + b + c = 8, we end up with:
-56 - 2(8), or
-56 - 16 = -40
The correct option is;
Coordinate grid shown from negative 2 to positive 2 on the x-axis and negative 2 to positive 2 on the y-axis in increments of 1 over 4. Only the whole numbers are labeled. A point A is shown at the intersection of 3 grid lines to the left of the y-axis and 6 grid lines above the x-axis
Answer:
A)58cm
B)
C)125.55square cm
Step-by-step explanation:
AB is a line is symmetry
Total length of left half part=12cm+9cm+3cm+5cm
Total length of left half part=29 cm
Length of left half part=Length of right half part
Therefore, length of right half part=29 cm
A) Perimeter of the shape=29cm+29cm=58cm
B)
Pythagoras theorem

Hypotenuse=12 cm
Base=5+3=8cm
In triangle ADC
Now, using Pythagoras theorem




C)
Area of shape=Area of triangle+ area of rectangle
Area of shape=
Where l=9cm
breadth=3+3=6cm
h=
base=2(5)+3(2)=16cm
Area of shape=
Area of shape=125.55 square cm
Answer:
