A triangle has a base length of 10 inches and a height of 4 inches.
What is the area of the triangle?
Answer:
No, The answer is 20. Remember area of triangle equals 1/2bh (or half of base and height multiplied.)
The area of triangle that has a base length of 10 inches and a height of 4 inches is 20 square inches.
What is area of a triangle?
The area of a triangle is one half the product of its base multiplied by height. Mathematically -
Area [Δ] = 1/2 x base x height
Given is a triangle (Δ) has a base length of 10 inches and a height of 4 inches.
We can write -
Base Length [B] = 10 inches
Height of triangle [H] = 4 inches
Area of triangle (Δ) = 1/2 x B x H
A(Δ) = 1/2 x B x H
A(Δ) = 1/2 x 10 x 4
A(Δ) = 20 square inches
Therefore, the area of triangle that has a base length of 10 inches and a height of 4 inches is 20 square inches.

4 in
5 in
Answer:
Option (B)
Step-by-step explanation:
Photo given in the picture has dimensions as,
Length = 4 in.
Width = 5 in.
This photo is the reduced form of a photo having dimension 16 by 20 inch print.
Since scale factor of an image is given by,
Scale factor = [tex]\frac{\text{Dimension of the image}}{\text{Dimension of the original picture}}[/tex]
= [tex]\frac{4}{16}[/tex]
= [tex]\frac{1}{4}[/tex]
Therefore, scale factor used to reduce the picture is [tex]\frac{1}{4}[/tex].
Option (B). will be the correct option.

What is the image of (2,8) after a reflection over the line y = x?
PLS ANSWER FAST
Ended up getting the answer wrong because the other person this is the correct answer.
(8,2)
Enjoy and Happy Holidays :)
The image of (2,8) after a reflection over the line y = x is (8, 2).
The given coordinate is (2, 8).
What is a reflection over the line y=x?Reflect over the y = x: When you reflect a point across the line y = x, the x-coordinate and y-coordinate change places.
When we reflect (2, 8) over the line y=x, we get the coordinate as (8, 2). Because the x-coordinate and y-coordinate changed places.
Therefore, the image of (2,8) after a reflection over the line y = x is (8, 2).

27 - 4x + -7 ( 1 + 3x)
Answer:
-25x + 20
Step-by-step explanation:
I am going to assume by the lack of instructions, you wanted this simplified. We need to start by combining the -7 into the two terms in the paranthesis:
27 -4x -7 -21x
We can now combine like terms to simplify:
-25x + 20
27-4x+-7(1+3x)
27 - 4x - 7(1+3x)
27 - 4x - 7 - 21x
-25x + 20

Which of these steps will eliminate a variable in this system? 4x-9y=8 2x+3y=24
For eliminate a variables we need addition method or elimination method.
Define the term Variable?In an equation or formula, a variable is a symbol or letter that stands in for an unknowable or varying quantity or value.
We can multiply the second equation by -2, so that the coefficient of x in both equations will be the same but with opposite signs:
⇒ 4x - 9y = 8
⇒ -4x - 6y = -48
Add the two equations together: ⇒ -15y = -40
⇒ y = 8/3
Substitute this value of y back into either equation to solve for x.
⇒ 4x - 9(8/3) = 8
⇒ 4x - 24 = 8
⇒ x = 8
Therefore, the steps to eliminate a variable in this system using the addition method are to multiply the second equation by -2, add the two equations together to eliminate the x variable, solve for y, and then substitute that value back into either equation to solve for x.
