What are the solution(s) to the quadratic equation 40 - x2 = 0?
O x = +2/10
O x = +4/10
O x = +2/5
x = +4V5
Answer:
±2sqrt(10)
Step-by-step explanation:
40 - x^2 = 0
Add x^2 to each side
40 -x^2 + x^2 = x^2
40 =x^2
Take the square root of each side
±sqrt(40) =sqrt(x^2)
±sqrt(4)sqrt(10) =x
±2sqrt(10) =x

What's the perimeter of rectangle DEFG, shown?
O A) 28
B) 34
C) 40
OD) 17
In the drawing below, line h is parallel to line k.
What is the value of y?
A. 135
B. 15
C. 35
D. 145
Answer:
D. 145
Step-by-step explanation:
the lines are parallel, so you can set the two expressions equal to each other:
2x + 5 = 3x - 10
x - 10 = 5
x = 15
then plug in x to the angle next to y: 2(15) + 5 = 35°
180 - 35 = 145°

HELP!!!!! Find each missing length to the nearest tenth.
Choose the step in which the first error occurs. Then evaluate the expression to find the correct answer.
3−(5−32+4)+6^2·(−2)
3−0+6^2·(−2) step 1
3−0+36·(−2) step 2
3−0+(−72) step 3
75 step 4
The first error occurs in step____ .
The value of 3−(5−32+4)+62·(−2) is ____.
Answer:
The first error occurs in Step 3
The value of the equation is -69
Step-by-step explanation:
The error is that 3-0+(-72) is actually supposed to be 3-0-72 because once you multiply the positive 36 and the negative 2, the equation automatically becomes negative.

Step-by-step explanation:
"Fifty-seven more than two times j"
Answer:
2j+57
Step-by-step explanation:
Two times a umber j is expressed as 2j
if Fifty-seven is more than two times j", this means we will have to add 57 to 2j as shown;
f(j) = 2j + 57
Hence the statement written as a function is expressed as 2j+57
A tool box has the dimensions of 9 in by 5 in by 6 in. If Kimberly plans to double one dimension to build a larger tool box, she believes she would double the volume of the tool box. Is she correct?
Answer:
She is correct.
Step-by-step explanation:
First, multiply 9 * 5 * 6 (original)
9 * 5 * 6
45 * 6
270 in³
Next, multiply 18 * 5 * 6 (if the length was doubled)
18 * 5 * 6
90 * 6
540 in³
Now divide 540 by 270.
540/270
2
Since the volume doubled, Kimberly is correct.
(You could do this for the other two and Kimberly is still correct.
If width was doubled
9 * (5 * 2) * 6 = 9 * 10 * 6
9 * 10 * 6 = 90 * 6
540
If height was doubled
9 * 5 * (6 * 2) = 9 * 5 * 12
45 * 12
540
540/270
2)
What is the approximate area of the shaded sector ?
Answer:
7.5 cm²
Step-by-step explanation:
Area of shaded sector = θ/360 × πr²
Where,
θ = 180° - 84° = 96°
r = ½(6) = 3 cm
Area of shaded sector = 96/360 × π × 3²
Area = 7.53982238 ≈ 7.5 cm²
