Answers

Step-by-step explanation:

You do Length x width x height right Prism

Prism or Cylinder = A is the area of the base x h the height.

Cube = s  is the length of the side.  V = s powered by 3

Prymid or cone = A  is the area of the base, h  the height.  V = 1/3Ah

Sphere = V = 4/3 πr powered by 3

This is all the volume I could remeber.

Kaylee is building a rectangular enclosure with an area of 90 square yards. She
wants the length of the enclosed area to be 6 yards longer than the width, x.
To represent this, she writes the equation x2 + 6x = 90. She then completes the
square to help solve her equation for x.
Which equation is equivalent to Kaylee's equation after she completes the square?
A.
(x + 3)2 = 93
B.
(x + 3)2 = 99
C.
(x + 6)2 = 96
D.
(x + 6)2 = 126

Answers

x^2 + 6x = 90

x^2 + 6x + 9 = 90 + 9

(x + 3)(x + 3) = 99

(x + 3)^2 = 99

Answer: B

The equation x² + 6x = 90 is also written as (x + 3)² = 99. Then the correct option is B.

What is the solution to the equation?

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

Kaylee is building a rectangular nook with an area of 90 square yards. She maintains that the length of the encased region should be 6 yards longer than the width, x. The equation is given below.

x² + 6x = 90

Add both sides 9, then we have

x² + 6x + 9 = 90 + 9

(x + 3)² = 99

The condition x² + 6x = 90 is likewise composed as (x + 3)² = 99. Then, at that point, the right choice is B.

More about the solution of the equation link is given below.

the answer to the first one is $7.60 because when you add $0.40 with $0.90, you get $1.30. because you have to add this to the money in the piggy bank, you would get $7.60; $6.30 + $1.30

Answer:

1.) 7.60

2.) 3.70

3.) 7.20

4.) 9.20

Step-by-step explanation:

6.30 + 0.40 + 0.90 = 7.60

Barrys has $7.60 total

3.20 + 1.60 = 4.80

8.50 - 4.80 = 3.70

Henrys change is $3.70

1.20 + (1.20 × 5)

1.20 + 6 = 7.20
