Answer:
The answer is 2. Because the dimensions of 1 cube is 1*1*1, the half cube is just half the width, so 2 half width = whole width of a unit cube
Step-by-step explanation:
Answer:
x = 13
Step-by-step explanation:
Since AB = AC , then Δ ABC is isosceles
So the base angles are congruent , both 2x + 15
The sum of the 3 angles = 180° , then
2x + 15 + 2x + 15 + 98 = 180
4x + 128 = 180 ( subtract 128 from both sides )
4x = 52 ( divide both sides by 4 )
x = 13
Answer:
c = -9 ±√8
Step-by-step explanation:
You can solve for (c+9)²=64 by using inverse operations. Since the expression (c + 9) is under the operation of squaring, use a square root on both sides to undo it. Then continue using inverse operations to solve for C.
(c+9)²=64
√(c+9)² = √8
(c + 9) = ±√8
c = -9 ±√8
Answer:
97
Step-by-step explanation:
Answer:
3x^2 - 3x - 3
Step-by-step explanation:
Plug in the equations in place of the variables
First, subtract k(x) from h(x)
x^2+1-x-2 (combine like terms)
x^2 - x -1
Next, multiply the new equation by 3
3(x^2 - x - 1) Use distributive property
= 3x^2 - 3x - 3
