Answer:
96 in²
Step-by-step explanation:
The surface area of the square pyramid is the area of the square base plus the area of the four triangular faces. The slant length is the height of each triangle.
A = s² + 4 (½ sL)
A = s² + 2sL
Given s = 6 and L = 5:
A = (6)² + 2(6)(5)
A = 36 + 60
A = 96
The area that needs to be painted is 96 in².
So because 9 and 10 are close to each other, and the fact that 10 is really easy to multiply by, you do 473 x 10 which is 4730, because you just add a 0 to the end.
This means that an estimate is 4730 or if you want to be less specific, <4730, because 9 is less than 10.
The actual product though is 4257.
Find y by maybe Pulling out like terms :
<span> 1.1 </span> Pull out like factors :
-y - 3 = -1 • (y + 3)
<span>Equation at the end of step 1 :</span><span>Step 2 :</span>Solving a Single Variable Equation :
<span> 2.1 </span> Solve : -y-3 = 0<span>
</span>Add 3 to both sides of the equation :<span>
</span> -y = 3
Multiply both sides of the equation by (-1) : y = -3
One solution was found : y = -3
