Answer:
391.2cm²
Step-by-step explanation:
Triangle = 1/2bh*2=1/2(4)(6.9)(2)=27.6 for each end triangle.
14*8=112 for each rectangular side.
112+112+112+27.6+27.6=391.2cm²
For 3 you have to subtract 72 on both sides
+72 -2X=54
-72 -72
72-72 cancels out and then subtract the 54 from -72 the answer for that then should be divided by -2
and then X= (the answer)
and the -72 goes under 54 not -2x
(-2d² + s)(5d² - 6s)
Simplify.
(-2d² × 5d²) + (-2d² × 6s) + (s × 5d²) + (s × -6s)
Simplify.
-10d² + (-12d²s) + (5d²s) + (-6s²)
Take out the parenthesis.
-10d² - 12d²s + 5d²s - 6s²
Combine like terms.
-10d² + (-12d²s + 5d²s) - 6s²
Simplify.
-10d² - 7d²s - 6s²
~Hope I helped!~
4 feet, the X-intercept tells us the value of X, aka how far the ball landed from 0
Well, it was good that you did subtract A from B to get
0=x^2-152x
then factor out the x (what do you mean it cannot be factored?)
0=x(x-152)
x=0 or 0=x-152 so x=152
so on day 0 and day 152
