Find two numbers that multiply to give ac and add to give b.Rewrite the middle with those numbersFactor the first two and last two terms separatelylet's try to do the first step
ac=10×1=10to figure out b we two factor of 10 that add up to -3
factor of 10:
1,2,5likewise
-1,-2,-5as you can see there's no factor that add up to -3 and multiply to give 10
hence,
the expression can't be factored

Mrs. Rodger got a weekly raise of $145. If she gets paid every other week, write an integer describing how the raise will affect her paycheck.
Answer:
Let the 1st paycheck be x (integer).
Mrs. Rodger got a weekly raise of $ 145.
So after completing the 1st week she will get $ (x+145).
Similarly after completing the 2nd week she will get $ (x + 145) + $ 145.
= $ (x + 145 + 145)
= $ (x + 290)
So in this way end of every week her salary will increase by $ 145.

A. Linear
B. Quadratic
C. Exponential
D. No pattern
Answer:linear
Step-by-step explanation:
it is a straight line
The best-fitting regression model for the scatterplot is linear. Thus, the correct answer is an option (A).
As per the given figure, the data points on a scatterplot, with the dependent variable (y-axis) plotted against the independent variable (x-axis).
Looking at the general pattern of the data points on the scatterplot.
Here, they follow a roughly linear trend.
This means that the data points roughly form a straight line or a curve that looks like a straight line.
Thus, the best-fitting regression model for the scatterplot is linear.
Hence, the correct answer is option (A).

How would you find the missing value? 15/4=5/x
15(4) = 5x
15(x) = 5(4)
15 14 =5+x
Using the intersecting chord theorem you multiply the two lengths of one line together to equal the multiplication of the two dimensions on the second line.
The answer would be 15(4) = 5x

7,10,3 how do I find the least common multiple
Answer:
Step-by-step explanation:
Usually you do it by factoring into primes. But this choice of numbers has no common primes, so all three make up the LCM
7 * 10 * 3
210 = LCM
LCM of 4 10 and 12
4: 2 * 2
10: 2 * 5
12: 2*2*3
LCM: 2 * 2 * 3 * 5 = 60
If you don't find the LCM then the answer would be 480
Answer:
210
Step-by-step explanation:
When finding the LCM(least common multiple) you need to factor each number into the product of prime number also called finding the prime factorization. Both 7 and 3 are prime, so they do not need to be factored further. However, 10 can be factored into 5 x 2.
3 - 3
7 - 7
10 - 5 x 2
By looking at the factors above, you notice none of them are the same, so none of the numbers share factors. This means you can just multiply all the factors to get the LCM:
3 x 7 x 5 x 2

Solve the equations for x:
x^2+nx-mx-nm=0
Answer:
x = [(m - n +/-√ (n^2 + m^2 + 2nm)]/2.
Step-by-step explanation:
x^2+nx-mx-nm=0
x^2 + (n - m)x - nm = 0
Using the quadratic formula:
x = [-(n - m) +/- √((n - m)^2 - 4*-nm)) / 2
= [(m - n +/- √ (n^2 + m^2 - 2nm + 4nm)]/2
= [(m - n +/-√ (n^2 + m^2 + 2nm)]/2

Problem:
The Winter fest Race will be held in December. A course was planned that
required runners to run 20 kilometers (km.) The race organizers planned the
race in 3 parts. Part 1 of the course is 4,000 meters (m). Part 2 of the race
is 6,000 meters (m.) Tommy said that there is no need for the Part 3 and that
Part 1 and 2 are 20 km. He is incorrect. How many meters will be required
for Part 3
Answer:
10,000m
Step-by-step explanation:
1 kilometer is equivalent to 1,000 meters. Therefore, we can find out why Tommy was incorrect and how many meters will be required for part 3 by converting the meters in this question to kilometers.
4,000m = 4km
6,000m = 6km
4km plus 6km is equal to 10km, which is nowhere near 20km. To find out how many kilometers we need for part 3, we need to subtract the number of kilometers we already have (10km) from the total number we need for the whole race (20km).
20km – 10km = 10km
Since the question is asking us to give the answer in meters, we need to multiply 10km by 1,000.
10km = 10,000m
The answer is 10,000m.9

A lenght of wire is bent to make a square of side 3.2 cm a: what is the length of wire in the square B: if the wire is silver costing 50 naira per centimetre what is the cost of the square C: 20 of the squares are linked together to make a necklace what does it cost to make the necklace
Answer:
12.8cm
640 naira
12,800 naira
Step-by-step explanation:
length of the wire is equal to the perimeter of a square
perimeter of a square = 4 x length
4 x 3.2 = 12.8 inches
cost of the square = length of the wire x 50
12,8 x 50 = 640
20 x 640 = 12800

What is the surface area of a right rectangular prism with the dimensions 4 m by 3 m by 10 m
Is the function below linear or non linear? y = 5 + 3(x-4)
Answer:
Linear
Step-by-step explanation:
The rule is that linear equations must have exponents of 1 (a sloped line) or 0 A verticle or horizontal line). This function can be simplified to
y = 3x - 12 + 5 = 3x - 7 which is the standard form of a linear equation
y - mx + b where m is the slope and m is the y intercept.
Miguel has a toolbox that measures 18 1/2 inches by 12 1/2 inches by 4 inches. Fill in the formula to find the volume of the toolbox
Answer:
925 cubic inches
Step-by-step explanation:
Miguel has a toolbox that measures 18 1/2 inches by 12 1/2 inches by 4 inches. Fill in the formula to find the volume of the toolbox
The toolbox is shaped as a Rectangular prism
The volume of a rectangular prism = Length × Width × Height
Hence,
Length = 18 1/2 inches
Width = 12 1/2 inches
Height = 4 inches
Volume of the toolbox =
18 1/2 inches × 12 1/2 inches × 4 inches
= 925 cubic inches
