Your answer would be 60 = 30 x 2 = 15 x 2 x 2 = 5 x 3 x 2 x 2= 5 x 3 x 2^2. I don't know the choices, but that is your answer.
Answer:
Exact Form: 23/4
Decimal Form: 5.75
Mixed Number Form: 5 3/4
Step-by-step explanation:
Hope this helps! <3
2|3x - 4| + 8 = 6 |subtract 8 from both sides
2|3x - 4| = -2 |divide both sides by 2
|3x - 4| = -1 FALS because for any number x: |x| ≥ 0
Answer: No solution ( x ∈ ∅)
Answer:
I suppose we want to find the side length of the square.
We know that:
The area of the square is 49cm^2
The distance between one of the vertices of the square and the middle of the square is:
BE = 4.95cm
Now let's remember some things.
For a square of side length L, the area is:
A = L^2
and the diagonal length is:
D = √(2)*L
In this case, we know that half of the diagonal is equal to:
BE = 4.95 cm
Then the diagonal is:
D = 2*BE = 2*4.95cm = 9.9cm
And for the diagonal formula, we have:
D = 9.9cm = √(2)*L
Then the side length is:
L = 9.9cm/√(2) = 7cm
And if we check the area of this square, is:
A = L^2 = (7cm)^2 = 49cm^2
So it checks.
Then we can conclude that the sidelength of the square is 7cm, which means that:
AB = 7cm
BC = 7cm
CD = 7cm
DA = 7cm

Step-by-step explanation:
For a, you need to plugin -9 into the equations inside the boxes and solve.
y = x^2 + 3, y = 9^2 + 3, y = 81 + 3, y = 84.
y = √x - 2, y = √9 - 2, y = 3 - 2, y = 1.
For b, It's only possible for the second equation to output 0, as for the first, it's impossible for x^2 to equal -3 and add to 3 to get 0. For the second equation you can plug in 4 to get 2 - 2, which gives 0.
