Its 272ft sq because if it is the area you can dig then you have to take away the No digging part and multiply the parts where you can dig.
Answer:
x = (+ - ) 9
Step-by-step explanation:
x^2 = 81
u know how u can sometimes cancel something out by doing the opposite.
This is one of those times as well. the opposite of ^2 = square root.
so if we take the square root of both sides, this will cancel out the^2 on the left side.
sqrt (x^2) = sqrt(81)
x = (+-) 9.....thats a positive and a negative sign...because the sqrt of 81 is both 9 and -9.
Area formula for a triangle is 1/2BxH
B=15
H=10
1/2(15)= 7.5
7.5 x 10= 75
So the area is 75 square cm :)
It’s D bc Dt= 15x3 and it’s not that hard to solve
The y-intercept is always the number at the end of a standard slope equation, so in your case, it’s - 3
