I’m this you should know that it is best to find the area of each triangle then add them together
As you see the base is 24 so you take half of 24 for the base of your triangles and you get 12
1/2 is one half
TRIANGLE A
A = 1/2( Base (times) height)
A = 1/2(12 (times) 35) = 210
The formula will be the exact same for the other triangle.
When adding the areas up you get 420 squared inches.
Therefore answering is 420 in^2
A number multiplied by 5, added with a number halved
I think this is right 26.98
35.50-20%-5% =26.98
Sorry if I’m wrong
Answer:
7 + 8 = 7 + 7 + 1.
Step-by-step explanation:
We know that, 'double plus one facts' is used to make the addition of numbers easy.
For e.g. we have 8 + 9 = 17. This addition can also be done as 8 + 8 + 1 = 17 i.e. we write first term twice and add 1 to get the result.
Hence, we give the name to this type of addition as 'double plus one'.
Now, we have to use this fact for 7 + 7.
So, we consider 7 + 8 = 15.
Therefore, 7 + 8 can be written as 7 + 7 + 1
Hence, the double plus one facts for 7 + 7 is 7 + 8 = 7 + 7 + 1.
