Answer:
3 and 7
Step-by-step explanation:
You know from your multiplication tables that ...
21 = 1×21 = 3×7
There are no other factorizations of 21 using integers. You may notice that the sums of these factors are ...
1+21 = 22
3+7 = 10 . . . . . . this is the pair of numbers you are looking for
The two numbers are 3 and 7.
Answer:
A, B, and E
Step-by-step explanation:
A. The terms 4x³ and 8x have a common factor (it is 4x)
B. The terms 4x3 and – 6x2 have a common factor (it is 2x²)
E. The polynomial can be grouped in different ways to factor by grouping.
( (4x³ - 6x²) + (8x - 12) ⇒ 2x²(2x-3) + 4(2x-3) ⇒ (2x²+4)(2x-3) )
The answer is -225.
9 times -25 is -225.
9*-25=-225
Answer:
7.5 30
45 180
Step-by-step explanation:
The given line has x = 1.25 and y = 5.
y/x = 5/1.25 = 4
x is multiplied by 4 to get y since 1.25 * 4 = 5.
That means the equation is
y = 4x
For a proportional function, every value of x must be multiplied by 4 to get y.
x = 7.5
y = 4x = 4(7.5) = 30
7.5 30
We need to find the values for the last line.
11 * 4 = 44
There is no 44
13.75 * 4 = 55
There is no 55.
17.5 * 4 = 70
There is no 70
30 * 4 = 120
There is no 120.
45 * 4 = 180
There is a 180.
45 180
Answer:
7.5 30
45 180
Just multiply 1/6 it's the scale factor so it'll tell you how you will shrink or enlarge the length
