Answer:
The longest side is 16 cm
Step-by-step explanation:
[tex]x + (x + 2) + (x + 4) = 42cm \\ x + x + 2 + x + 4 = 42cm \\ 3x + 6 = 42cm \\ 3x = 36cm \\ x = 12[/tex]
check and finish
[tex]12 + (12 + 2) + (12 + 4) = 42cm \\ 12 + 12 + 12 + 6 = 42 cm\\ 36 + 6 = 42cm \\ 42cm = 42cm[/tex]
lengths of sides
[tex]12 + 4 = 16cm \\ 12 + 2 = 14cm \\ 12cm[/tex]

A jar has 4 red marbles 7 blue marbles and 8 yellow marbles what is the probability of randomly selecting a marble and getting a blue marble?
Please help!!!!
Explanation:
There are 7 blue marbles out of 4+7+8 = 11+8 = 19 total
The probability of selecting blue is therefore 7/19
We cannot reduce 7/19 any further because 7 and 19 have no common factors other than 1.

Answer:
A) a = 25
B) b = 14
Step-by-step explanation:
hopefully this helps :)
Solve the following:
[tex] \\ \sf \: a) \: \: \frac{a}{5} + 3 = 8[/tex]
[tex] \\ \sf \: b) \: \: \frac{3b}{7} - 1 = 5[/tex]
Solution:-Solving question a) :
[tex] \\ \sf \frac{a}{5 } + 3 = 8[/tex]
[tex] \\ \sf \mapsto \frac{a + 15}{5} = 8[/tex]
[tex] \\ \sf \mapsto \: a + 15 = 8 \times 5[/tex]
[tex] \\ \sf \mapsto \: a = 40 - 15[/tex]
[tex] \\ \sf \mapsto \: a = 25[/tex]
[tex] \\ \sf \therefore \: a = 25[/tex]
Solving question b) :
[tex] \\ \sf \frac{3b}{7} - 1 = 5[/tex]
[tex] \\ \sf \mapsto \: \frac{3b - 7}{7} = 5 [/tex]
[tex] \\ \sf \mapsto3b - 7 = 5 \times 7[/tex]
[tex] \\ \sf \mapsto3b = 35 + 7[/tex]
[tex] \\ \sf \mapsto \: b = \frac{42}{3} [/tex]
[tex] \\ \sf \mapsto \: b = 14[/tex]
[tex] \\ \sf \therefore \: b = 14[/tex]
Answer:-a = 25
b = 14
the quadratic x2-4x-21 can be witten in the form (x+a)2 +b find the values of a and b
(x-2)^2-25
How?
[tex]\\ \sf\longmapsto (x-2)^2-25[/tex]
[tex]\\ \sf\longmapsto x^2-4x+4-25[/tex]
[tex]\\ \sf\longmapsto x^2-4x-21[/tex]
Answer:
a = - 2, b = -25Step-by-step explanation:
Given quadratic expression:
x² - 4x - 21Convert this into vertex form:
x² - 4x + 4 - 25 = (x - 2)² - 25Compare this with the vertex form to determine the values of a and b:
a = - 2b = -25Amanda recorded the temperatures at which two oils freeze:
Oil Temperature
Olive oil −6.1 °C
Peanut oil 3.1 °C
Which statement about the temperatures at which these oils freeze is true?
A Peanut oil freezes at a lower temperature than olive oil because 3.1 °C < −6.1 °C.
B Peanut oil freezes at a higher temperature than olive oil because 3.1 °C < −6.1 °C.
C Peanut oil freezes at a lower temperature than olive oil because 3.1 °C > −6.1 °C.
D Peanut oil freezes at a higher temperature than olive oil because 3.1 °C > −6.1 °C.
Answer:
It's C, Peanut oil freezes at a lower temperature than olive oil because 3.1 > -6.1
help asap plsssssssssssssssssssssssssss. Find the missing parts of each number line. Assume that the lines have been split into equal parts.
Answer:
16 for the first one. each segment is 4
40 for the second. each segment is 8
Answer:
0, 4, 8, 12, 16
8, 16, 24, 32, 40, 48
Step-by-step explanation:
The first number line has 6 parts. 24÷6=4. Each vertical line will increase by 4.
So starting at 0, the parts of the number line are:
0, 4, 8, 12, 16, 20, 24
The specific part being asked for is 0, 4, 8, 12, 16
The second number line has 8 parts. 64÷8=8. Each vertical line will increase by 8.
Starting at 0, the parts of the number line are:
0, 8, 16, 24, 32, 40, 48, 56, 64
The specific part being asked for is 8, 16, 24, 32, 40, 48

Find the slope of the line containing the pair of points. (7,4) and (6,-9)
Answer:
13
Step-by-step explanation:
We can use the slope formula to find the slope
m = ( y2-y1)/(x2-x1)
= ( -9-4)/(6-7)
= -13/-1
= 13

Can anyone please help me solve this?
Answer:
y = 9, x = -2
Step-by-step explanation:
1. (9y+4) and (11y-14) are the same size angle, so you can set them equal to each other:
9y+4=11y-14
2. Solve for y:
4=2y-14
18=2y
9=y
3. (3x+28) and 63 together are opposite to (9y+4) so you can set them equal to each other:
(3x+28)+63=(9y+4)
4. You know that y=9, so plug in 9 for y and solve for x:
3x+28+63=9(9)+4
3x+91=85
3x=-6
x=-2

Step-by-step explanation:
Which equation matches the graph of the greatest integer function given
below?
Answer:
D. y = [x] - 2
Explanation:
The Greatest Integer Function is denoted by y = [x].
For all real numbers, x, the greatest integer function returns the largest integer less than or equal to x. In essence, it rounds down a real number to the nearest lowest integer.
In the plot of y = [x], the plot starts from origin because y = [0] = 0.
But, in the question, all the lines are shifted 2 units downward, as it starts from (0, -2).
i.e for every values of x, y moves two units down
So our answer is y = [x] - 2.

Hope this helps, good luck! :D
[ SIDE NOTE: Someone else said that it is y=[x]-4, so I am not 100% sure! ]
I honsetly don't even know.
Step-by-step explanation:
the correct answer is B. [-5, -3]
for x = -5 => f(-5) = 2(-5)²-5
= 50-5
= 45
for x = -3 => f(-3) = 2(-3)² -5
= 18-5
= 13
the change = 45-13 = 32
(this is the greatest)
[-5,-3]
Let's verify
f(-5)
2(-5)²-52(25)-545f(-3)
2(-3)²-52(9)-518-513Rate of change
f(-5)-f(-3)/-5-345-13/-8-4The value of y is directly proportional to the value of x. Given y = 12 when x = 36.

Can you y’all help me with this. i need to know what is the domain and range from this graph. i’m kinda confused for this
Answer:
The answer is below:
Step-by-step explanation:
The range is everything under and including 6 as we see that it will forever go to numbers under or equal to 6.
The range is all real because the lines will keep on going to infinity and negative infinity
Domain: All Real
Range: y is greater than or equal to 6
