Answer: 151
Step-by-step
you need to first find the area of each piece of the tent
the 2 rectangular flaps would be 6*8= 48 each
the bottom would be 4*8=32
to find the area of the triangular pieces we need to know the height of each triangle, right now we only know sides. To find the height (the altitude) you draw a line straight down to make a 90 degree angle.
that will also cut your base in half (2 instead of 4) and make 6 your hypotenuse
now use the Pythagorean theorem to find the height of the triangle

Area of a triangle is

the area of one triangle is 11.31
so together it is 48+48+32+11.31+11.31= 150.6
round up to 151
Note: In option A, it should be "+" instead of "(".
Given:
The expression is

To find:
The equivalent expression.
Solution:
We have,

Using distributive property, we get


On combining like terms, we get


The expression
is equivalent to the given expression.
Therefore, the correct option is A.
There is only the number 7 in this question I can’t really help with one number
First find the total of the ratio:
7 + 3 = 10
Now we can divide 60 by 10:
60 divided by 10 is 6
Finally we can multiply both 7 and 3 by 6:
7 x 6 = 42
3 x 6 = 18
To check we can add 42 and 18: this gives us 60.
Answer: 42:18
Hope this helps!
