20 points solve (x-3)(x^2+3x+9)=37

Answers

Answer 1

Answer:

the answer is x = 4.

1. use the quadratic formula.

2. use a coordinate plane to check your answer.

hope this helps.

Answer 2

Answer:

x = 4

Step-by-step explanation:

(x - 3)(x² + 3x + 9) = 37 ← distribute left side

x³ + 3x² + 9x - 3x² - 9x - 27 = 37 , simplify left side by collecting like terms

x³ - 27 = 37 ( add 27 to both sides )

x³ = 64 ( take cube root of both sides )

x = [tex]\sqrt[3]{64}[/tex] = 4

What is the area of a semicircle with a diameter of 8 feet? Estimate using 3.14 for TT
A) 25.12 ft ²
B) 50.24 ft²
C)200.96 ft ²
D) 100.48 Ft²​

Answers

Answer: 25.12 ft²

Step-by-step explanation:

So  r = D ÷ 2

Since the area of a circle = πr²

then the area of a semi-circle =  (¹/₂π (¹/₂D)²)

Area of a semicircle given the diameter = (¹/₂π (¹/₂D)²)

                                                                  =  (¹/₂(3.14) (¹/₂ 8ft)²)

                                                                  = 25.12 ft²

Hope this helps!

Answer:

Step-by-step explanation:

G. 10x3=3x10     1. Commutative property of multiplication

3. Associative property of Addition

F. (5x3)x4=5x(3x4)     4.Associative property of multiplication

J. If 11 = y then y = 11      5. Symmetric property

A. 21=21       6. Reflexive property

7. Transitive property

8. Zero property of multiplication

9. multiplicative inverse

D. 9x0=0    10. Zero property of multiplication

E. 4+0=4     11. Additive identity

H. 19x1=19   12. Multiplicative identity

B. If k=15 and 5 = 3m. Then k = 3m    This statement is not true.

This may be the transitive property, but this was written incorrectly. You have 15 in k = 15, but 5 in 5 = 3m.

C. 7+4=4+7      This is commutative property of addition, which is not listed above

I. 8x1/2=1     This statement is false. Maybe you meant 8 x 1/8 = 1. Then it is 9. Multiplicative inverse.

K. (6+2) + 1 = 6 + 2 + 1 This does not illustrate anything.

Maybe you missed the parentheses on the right side: 6 + (2 + 1). Then it is the associative property of addition.

L. 2+(2-)=0 If this were 2 + (-2) = 0, then it would be Additive Inverse, but I don't see this listed above.

The length and breadth of a rectangle are (2x + 1) cm
and (x + 3) cm, respectively. If the area of the
rectangle is 88 cm^2 ,find:
a. the value of x
b. the perimeter of the rectangle.

Answers

Answer:

Step-by-step explanation:

Area = 88 sq.cm

length * width = 88

(2x + 1)(x + 3)  = 88

2x*(x +3) + 1*(x + 3) = 88

2x*x + 2x*3 + x + 3= 88

2x² + 6x + x + 3 = 88

2x² + 7x + 3 - 88 = 0

2x² + 7x - 85 = 0

2x² - 10x + 17x - 85 = 0

2x(x - 5) + 17(x - 5) =0

(x - 5)(2x + 17 )= 0

x - 5 = 0      {Ignore 2x +17 = 0 as it gives a negative value}

x = 5

b) length = 2x + 1 = 2*5 + 1 = 10 +1 = 11 cm

breadth = x+ 3 = 5 + 3 = 8 cm

Perimeter = 2*(length +breadth}

                = 2* (11 + 8)

                = 2 * 19

               = 38 cm

|1 + 2x| + |5 − 3x| − |−5x − 8 | , is x < −10
Simplified expression is:

Answers

Answer:

steps below

Step-by-step explanation:

x < -10

|1+2x| < 0      ∴ |1+2x| = -(1+2x)

|5 − 3x| > 0   ∴ |5 − 3x| = 5-3x

|−5x − 8 | > 0   ∴ |−5x − 8 | = -5x-8

|1 + 2x| + |5 − 3x| − |−5x − 8 |

= -(1+2x) + (5-3x) - (-5x-8)

= (-2x - 3x + 5x) + (-1 + 5 + 8)

Four points are P(0,4), Q(0,3), R(2,0), S(0,5). Which three of them are collinear?​

Answers

Answer: P, Q and S

In other words, everything but point R.

============================================================

Explanation:

The term "collinear" means "points that fall on the same straight line". Any two points are always guaranteed to be collinear; however the same can't be said for any 3 random points.

In this case, points P, Q and S are all on the vertical y axis which is why they are collinear.

The grocery store carries diapers for children. Each diaper container has 48 diapers. Two dozen babies each need a container of diapers. How many diapers are needed?

Answers

Answer:

1152 diapers are needed

Step-by-step explanation:

2 dozen babies is equall to 24 babies

-(1 dozen is 12 babies)

If 24 babies need a package of diapers which includes 48 diapers, we need to multiply 24x48 which equals 1152 diapers

Answer:1152

Step-by-step explanation:1 DOZEN MEANS 12 SO 2 DOZEN IS 12*2WHICH IS 24

NUMBER OF DIPER A BABY WOULD NEED  IS 48

NUMBER OF BABIES IS 12*2 =24

THEREFORE IF 24 BABIES EACH WOULD REQUIRE A CONTAINER WITH 48 DIPERS TOTAL NUMBER OF DIPERS NEEDED IS 24*48 WHICH IS 1152
