What is the surface area of a square pyramid that has a base length of 5 inches and triangular faces that are 9 inches tall
scZoUnD [109]

Answer:

115 in²

Step-by-step explanation:

SA = Area of triangular surfaces + area of the square base

SA= 2bh + b²

SA = 2(5)(9)+5²

SA = 90+25

SA = 115

Which expressions are completely factored? Select each correct answer. 18y^3−6y=3y(6y^2−2) 32y^10−24=8(4y^10−3) 20y^7+10y^2=5y(4
Vladimir79 [104]

Answer:

The expressions that completely factored are:

32y^{10}-24 = 8(y^{10}-3) ⇒ 2nd

16y^{5}+12y^{3}=4y^{3}(4y^{2}+3) ⇒ 4th

Step-by-step explanation:

Complete factorization means the terms in the bracket has no common factor

∵ The expression is 18y³ - 6y

- Find the greatest common factor of the numbers and the variable

∵ The greatest common factor of 18 and 6 is 6

∵ The greatest common factor of y³ and y is y

∴ The greatest common factor is 6y

- Divide each term by 6y to find the terms in the bracket

∴ 18y³ - 6y = 6y(3y² - 1) ⇒ not the same with the answer

∵ The expression is 32y^{10}-24

∵ The greatest common factor of 32 and 24 is 8

∴ The greatest common factor is 8

- Divide each term by 8 to find the terms in the bracket

∴ 32y^{10}-24 = 8(  y^{10}-3)  ⇒ the same with the answer

∴ The expression 32y^{10}-24 = 8(y^{10}-3) is completely factored

∵ The expression is 20y^{7}+10y^{2}

∵ The greatest common factor of 20 and 10 is 10

∵ The greatest common factor of y^{7} and y² is y²

∴ The greatest common factor is 10y²

- Divide each term by 10y² to find the terms in the bracket

∴ 20y^{7}+10y^{2}=10y^{2}(2y^{5}+1) ⇒ not the same with the answer

∵ The expression is 16y^{5}+12y^{3}

∵ The greatest common factor of 16 and 12 is 4

∵ The greatest common factor of y^{5} and y³ is y³

∴ The greatest common factor is 4y³

- Divide each term by 4y³ to find the terms in the bracket

∴ 16y^{5}+12y^{3}=4y^{3}(4y^{2}+3) ⇒ the same with the answer

∴ The expression 16y^{5}+12y^{3}=4y^{3}(4y^{2}+3) is completely factored

The expressions that completely factored are:

32y^{10}-24 = 8(y^{10}-3)

16y^{5}+12y^{3}=4y^{3}(4y^{2}+3)

The perimeter of a rectangular painting is 312 centimeters. If the width of the painting is 64 centimeters, what is its length?
Kay [80]
Perimeter= 2L + 2W
312 cm= 2L + 2(64)
312= 2L + 128
subtract 128 from both sides
184= 2L
divide both sides by 2
92 cm= L

ANSWER: The length is 92cm.

Hope this helps! :)

For what values of x will make the following statement true?
Serhud [2]

The value of x that will make the statement true is 1

Step-by-step explanation:

The given is:

  • f(x) = x - 4
  • g(x) = 2x + 3

We need to find the value of x which makes [f(x) + 2g(x)] = 7

∵ f(x) = x - 4

∵ g(x) = 2x + 3

∵ f(x) + 2g(x) = 7

- Multiply g(x) by 2

∵ 2g(x) = 2(2x + 3) = 2(2x) + 2(3) = 4x + 6

∴ 2g(x) = 4x + 6

∵ f(x) + 2g(x) = 7

∴ (x - 4) + (4x + 6) = 7

- Add the like terms in the left hand side

∴ (x + 4x) + (-4 + 6) = 7

∴ 5x + 2 = 7

- Subtract 2 from both sides

∴ 5x = 5

- Divide both sides by 5

∴ x = 1

The value of x that will make the statement true is 1
