I think that since it says that f:x is |3x-7| and for i. it is f(-1), I believe it is suggesting/telling that x=-1 or f(-1) so |3*(-1)-7|. I don't know for sure but I believe it is 10.

Find the area of a square with a side measure of 3x − 6 feet. Question 5 options: 9x2−36x+36 sq. ft. 9x2−6 sq. ft. 9x2+36x+36 sq

Sergeeva-Olga [200]

Answer:

9x^2 - 36x + 36 sq. ft. (the first option).

Step-by-step explanation:

Area of a square of side d = d^2.

So area of this square = (3x - 6)^2

= (3x - 6)(3x - 6)

= 3x(3x - 6) - 6(3x - 6)

= 9x^2 - 18x - 18x + 36

= 9x^2 - 36x + 36 sq ft.

students are painting a mural so far the mural is painted 1/4 blue ,2/8 red and 3/12 green use fraction strips to determine how

Fofino [41]

------------------------------------------------------------------------------------
Reduced (simplify) all factions if possible
------------------------------------------------------------------------------------

(1/4 cannot be reduced)
1/4 = 1/4

(divided by 2 for both numerator and denominator)
2/8 = 1/4

(divide by 3 for both numerator and denominator)
3/12 = 1/4

------------------------------------------------------------------------------------
Find combined fraction of the mural that has been painted.
------------------------------------------------------------------------------------
1/4 + 1/4 + 1/4 = 3/4

------------------------------------------------------------------------------------
Answer: 3/4 of the mural has been painted.

This figure consist of a rectangle a semi circle and a quarter circle what is the perimeter of this figure use 3.14 for pi

alexandr402 [8]

Answer:

37.55 m

Step-by-step explanation:

To find the perimeter, we have to add the lengths of each part of the figure.

We start from the circle on top. We see that its diameter is 10 m, therefore its radius is

r = 5 m

(because the radius is half the diameter). The perimeter of a circle is given by

$p=2 \pi r$
