Answer:the first option

Step-by-step explanation:

Answer:

1

Step-by-step explanation:

To find the solutions (or, in other words, zeroes) of a quadratic function/equation we use the discriminant (the part that's inside the square root of the quadratic formula, [tex]b^2-4ac[/tex].)

If the discriminant is smaller than 0, there are no zeroes

If the discriminant is equal to 0, there is one zero

If the discriminant is larger than 0, it has two zeroes

The discriminant is commonly denoted as [tex]\Delta[/tex].

Answer:

she has eaten 14 times because each time she ate 2 she gave away 5, that means she had to give out 7 times- 7*5 =35 so all you have to do is multiply 2 by 7 because she ate TWO each time she gave out 5!

Answer:

im not sure but i think its correct (like 80-90%)(but probably not but u can use this method to find the correct answer)

Step-by-step explanation:

a) 25+40= 65 (x) 10= 650/2= 325

b) 325 (x) 50= 16,250cm

c) 325 (x) 2= 650

20 (x) 50= 1000

50 (x) 40= 2000

15 (x) 50= 750

25 (x) 50= 1250

then, just add eveything above should be 5,650cm^2

Answer:

Option B

Step-by-step explanation:

In a triangle , sum of measure of any 2 sides is always greater than the measure of the third side. So

[tex]5 + 12 > k[/tex]

[tex] = > 17 > k[/tex]

Hence the measure of k is less than 17.

In the triangle , measure of the longest side is 12 cm. As we know that sum of measure of any 2 sides of triangle is greater than the measure of third side , the value of k should be more than 7cm because if the value of k would be 7 , then 5 + 7 = 12 and the sum will get equal to the measure of longest side , hence such triangle wont exist.

Atlast , the range of k is :-

[tex]7 < k < 17[/tex]

Answer:

x³ + 3

Step-by-step explanation:

Given

[tex]x^{8}[/tex] + 3[tex]x^{5}[/tex] ← factor out [tex]x^{5}[/tex] from each term

= [tex]x^{5}[/tex](x³ + 3 )

Answer:

x^3 + 3

Answer: 10 people can/ 12.50+16.25x is less than or equal to 175

Step-by-step explanation: so parking is constant since it doesn't change. ticket price however is affected by a variable which represents ticket per person which is shown as 12.50(parking)+16.25x where x would equal the max amount of people while respecting the given 175 limit we cannot go over

Answer:

£6886

Step-by-step explanation:

P x e^r x t is the formula for compound interest

P x e^0.05 x 3 = 8000

P x 1.162 = 8000

P = 6885.66 = £6886 (round to the nearest pound)

Answer:

8x

Step-by-step explanation:

perimeter is sum of all sides

square has 4 equal sides

each side measures '2x'

2x + 2x + 2x + 2x = 8x   or   4(2x) = 8x

Answer: -1

Step-by-step explanation: First, factor out 3.6. You should get -m+3. Since the coefficient is just the number being multiplied to the variable (which is m here), your coefficient should be -1 because m is being multiplied to -1 to make -m. Hope this helps!

Answer:

The formula for area of a rectangle is: A = L * W where L is the length and W is the width. where S is the length of one side.

The expression A=LW is used to find the area of the rectangle.

We have to determine

The expression can you use to find the area of the rectangle.

The formula for the area of a rectangle is: A = L * W

where L is the length and W is the width.

where S is the length of one side.

Answer:

Line m and n are parallel lines that are intersected by a line

This means that corresponding angles in each line are equal to each other

This means that angle (3x+58) is equal to (5x)

now, we can solve for x and from there find the angle measure

(3x+58)=5x

3x-3x+58=5x-3x

58=2x

58/2=2x/2

29=x

if 29=x then 5(29)=5x

the angle measure of these angles is 145

Step-by-step explanation:

Answer:

Step-by-step explanation:

m // n  and they are intersected by transversal.

Corresponding angles are equal

5x = 3x + 58

5x - 3x = 58

     2x = 58

      x = 58/2

x = 29

Answer:

30 units²

Step-by-step explanation:

The area (A) of a parallelogram is calculated as

A = bh ( b is the base and h the perpendicular height )

Here

b is the horizontal measure between 2 red points, that is 6

h is the vertical measure from the lower left point to the other horizontal line, that is 5, then

A = 6 × 5 = 30 units²
