Answer 1

Answer:

C.  [tex]x=-9 \textsf{ and }x=1[/tex]

Step-by-step explanation:

[tex](x+4)^2=25[/tex]

[tex](x+4)(x+4)=25[/tex]

expand the brackets:

[tex]x^2+8x+16=25[/tex]

subtract 25 from both sides:

[tex]x^2+8x-9=0[/tex]

factor:

[tex]x^2+9x-x-9=0[/tex]

[tex]x(x+9)-1(x+9)=0[/tex]

[tex](x-1)(x+9)=0[/tex]

solve for x:

[tex]x-1=0 \implies x=1[/tex]

[tex]x+9=0 \implies x=-9[/tex]

5 × 10=50

5+5+5+5=20

there your answer

Step-by-step explanation:

you slow -_-

Answer : 5 x 4 (Option C)

Step-by-step explanation :  5 + 5 + 5 + 5 = 20

                                            By trial & error method, we get

                    5 x 2 = 10 ≠ 20

                    5 x 4 = 20

                    5 x 5 = 25 ≠ 20

                    5 x 10 = 50 ≠ 20

Hence 5 x 4 is the right answer

You can either follow the trial & error method or the following method !!

5 + 5 + 5 + 5 has ' 4 ' fives

Hence, 5 + 5 + 5 + 5 = 5 (since it is the no) x 4 (since it is the no of times 5 is repeating)

Hence 5 x 4 is the right answer

Answers

Answer:

The answer is 6

Step-by-step explanation:

2.3... where the 3s go on forever is the same as 2 + 1/3 or 2 & 1/3  

The whole number portions add to 3+2 = 5, and we add on the carry of 1 to get 5+1 = 6

3 & 2/3 = 3 + 2/3 = 3 + 0.667 = 3.667 approximately

adding this onto 2.333 leads to

3.667 + 2.333 = 6

Technically the 6's go on forever in the decimal form of 3 & 2/3, but rounding wont have an effect on the answer when we add

The equation 4(x – 3)2 – 5 = 139 has two solutions: one positive and one negative. What is the
negative solution?
7.

Answers

Answer:

Step-by-step explanation:

4(x-3)2-5 = 139

(4x-12)-5=139

-20x + 60 = 139

-20x +60 - (60) = 139- 60

-20x = 79 divide both sides by -20

x = -3.95

what is the approximate height of the rice container if the radius is 2.5 in. and the volume is 235.5 in cubed​

Answers

Answer:

12 in

Step-by-step explanation:

r = 2.5 in

V = 235.5 in³

Find h

Use V = πr²h

so 235.5 = 3.14 * 2.5² * h

235.5 =  19.625 h

h = 235.5/19.625 = 12 in

The area of a rectangle is 75 square feet, and the length is 25 feet. What is the perimeter?

(3+25)x2+56 feets

Answer:

75ft.

Step-by-step explanation:

What you do is subtract two 25s from the area (because there are two sides for length) which gives you 25. The width would be half of that which is 12.5. Then add two widths (12.5+12.5=25), and add that to two lengths (25+25=50). The answer is 75ft as well. Please tell me if I'm wrong.
