What is (2x + 1)(3x + 7) simplified

Mathematics
2 answers:
AysviL [449]2 years ago

Answer:

6x^{2}+17x+7 and zeros are -7/3 and -1/2

Step-by-step explanation:

You multiply every property by every variable not in their own parentheses.

2x*3x=6x^2

2x*7=14x

3x*1=3x

7*1=7

6x^2+3x+14x+7

add like variables together 3x+14x

6x^2+17x+7

( To get the zeros just make each equation in the parentheses equal to zero and solve for x.) ex 2x+1=0   x=-1/2

Answer:

The table will be:

x |-2 | -1 | 0 | 1 | 2  

y | 1  | 4 | 5 | 4 | 2

Step-by-step explanation:

The function is:

y=5-x^{2}

a) The x values of the table is:

x |-2 | -1 | 0 | 1 | 2

So, when x = -2, y will be:

y(-2)=5-(-2)^{2}=5-4=1

Doing the same with the other x values we have:

y(-1)=5-(-1)^{2}=5-1=4

y(0)=5-(0)^{2}=5

y(1)=5-(1)^{2}=5-1=4

y(2)=5-(2)^{2}=5-4=1

The table will be:

x |-2 | -1 | 0 | 1 | 2  

y | 1  | 4 | 5 | 4 | 1

I hope it helps you!

Create a factorable polynomial with a GCF of 2. Rewrite that polynomial in two other equivalent forms. Explain how each form was
earnstyle [38]
 4x^2 + 8x + 12

Equivalent forms: x^2 + 2x + 3 and 8x^2 + 16x + 24.

The first equivalent form was created by dividing each term by 2, and the second equivalent form was created by multiplying each term by 2.

HELP ME PLEASEEEEEEEE ASAPPPP !!
OLEGan [10]

Answer:

C and D

Step-by-step explanation:

Mathematically, a unit circle is one in which the value of the radius is 1 unit

Generally, for a unit circle we have it that;

r^2 = x^2 + y^2

where (x,y) represents the coordinates of a point on the unit circle

But from above, r = 1

Thus:

x^2 + y^2 = 1

Looking at option C, by squaring each coordinate, we have

(6/7)^2 = 36/49 and the second as 13/49

by adding both, we have

36/49 + 13/49 = 49/49 = 1

Thus, we have this as a coordinate on the unit circle

For the last option;

(5/13)^2 = 25/169 and (12/13)^2 = 144/169

Adding both, we have;

25/169 + 144/169 = 169/169 = 1

So this is also a point on the unit circle

Think About the Process The diameter of a cylinder is 5 yd. The height is 4 yd. What is the first step to finding the volume of
frez [133]

Answer:

C

Step-by-step explanation:

Formula for volume of cylinder is :

  • V = πr^2h
  • We want to know Volume, now we have:
  • Diameter (d) , and r = d/2
  • Height
  • So the first step is use diameter to find the radius
