To solve this, we must know the formula for surface area of a rectangular prism. The formula solves for 3 of the faces, and then multiplies by 2, because in a rectangular prism, 2 opposite sides will always be equal.
The formula is 2(wl+hl+hw)
Now all we have to do is substitute in our values and solve.
2(wl+hl+hw)=
2(12*11+11*11+11*12)=
2(385)=
770=
Using the math above, we can see that the correct answer is A. 770 square cm.
Answer:
The 16ᵗʰ term of this sequence is 82
Step-by-step explanation:
Here,
First Term = a₁ = 9
Common Difference = (d) = 2
Now, For 16ᵗʰ term, n = 16
<em>aₙ = a + (n - 1)d</em>
a₁₆ = 7 + (16 - 1) × 2
a₁₆ = 7 + 15 × 5
a₁₆ = 7 + 75
a₁₆ = 82
Thus, The 16ᵗʰ term of this sequence is 82

Red has a greater value.
Blue = -2
Red = 3
$800 increased by 25% = 1.25 x 800 = $1,000
Answer:
-49
Step-by-step explanation:
In order to fill in the given expression, we need to know ...
- f(-2) = -4
- f(-3) = 5
- f(-4) = 7
- g(0) = -7
- g(-3) = 3
Then the expression is ...
√(5 -(-4)) -(-7)² +7÷(-7)·(3) = √9 -49 +7/(-7)(3)
= 3 -49 +(-1)(3) = 3 -49 -3
= -46 -3 = -49
