Gerard is calculating the area of a composite figure. The figure is made up of a square with side lengths of 6 centimeters (cm) and a triangle with a base of 6 cm and a height of 3.5 cm.
Gerard multiplies 6 by 3.5 to get that the area of the figure is 21 cm2, which is not the correct area.
Which statement correctly describes how Gerard could have found the correct answer?
-He should have found the area of the square, 36 cm2, and added it to the area of the triangle, 27 cm2, to get 63 sq. cm.
-He should have added 6 to 3.5 to get 9.5 sq. cm.
-He should have multiplied 21 by 12 to get 10.5 sq. cm.
-He should have found the area of the square, 36 cm2, and added it to the area of the triangle, 10.5 cm2, to get 46.5 sq. cm.
HELP PLEASE
The correct statement is Gerard should have found the area of the square, 36 cm², and added it to the area of the triangle, 10.5 cm², to get 46.5 sq. cm.
What is Area?Area of a geometrical shape or figure in two dimension is the space which lies within the boundary of the shape.
The given composite figure composed of a triangle and a square.
So, we should find the area of both the triangle and the square and add it to get the area of the composite figure.
Let A₁ and A₂ be the area of the square and area of the triangle respectively.
Area of a square with side lengths 'a' = a²
Here, length of the side of the square = 6 cm
A₁ = 6² = 36 cm²
Area of a triangle with base 'b' and height 'h' = [tex]\frac{1}{2}[/tex] × b × h
Here, b = 6 cm and h = 3.5 cm
A₂ = [tex]\frac{1}{2}[/tex] × 6 × 3.5 = 10.5 cm²
Area of the composite figure = A₁ + A₂
= 36 cm² + 10.5 cm²
= 46.5 cm²
Hence Gerard could have found the correct answer by finding the area of the square as 36 cm², and adding it to the area of the triangle, 10.5 cm², to get the area of the figure as 46.5 cm².

write down the inequality shown on the number line.
Answer:
The inequality on the number line shown is {x:x<2}
The inequality shown on the number line is represented by the relation x<2.
As, the inequality on a number line, the notation includes the open circle at 2.
This means that the value of 2 itself is not included in the set of solutions.
In the notation "x < 2," the symbol "<" indicates "less than," and the number 2 is the upper bound of the inequality.
Since the inequality is strict, use an open circle to show that the point 2 is not part of the solution set.
Therefore, the inequality is "x < 2".

Angle B and angle C are supplementary. If the measure of angle B is 14 times the measure of angle C, what is the difference between the angles' measures?
Enter your answer as the correct number of degrees, like this: 42
HELP PLEASEEEEEE
Answer:
156°Step 1: Create an Equation Using the idea (Angle B + Angle C = 180°)
=> 14x + x = 180°
Step 2: Solve.
=> 14x + x = 180°
=> 15x = 180°
=> x = 12°
Step 3: Multiply 12 by 14.
=> 12 x 14 = 168°
Step 4: Subtract 168 by 12.
=> 168 - 12
=> 156°
Final Answer:
After working on this problem, we can conclude that the difference between Angle B and Angle C is 156°

Find an equation of a line perpendicular to the given line and contains the given point. Write the equation in slope-intercept form.
y = ?
Answer:
y = -1/5 x -2
Step-by-step explanation:
Given line y = 5x - 1
as in slope intercept form m = 5
point (5, -3)
for two lines to be perpendicular product of slopes must be -1\
so for new line slope is
m1 * m2 = -1
5 * m2 = -1
m2 = -1/5
line equation is y - (-3) = -1/5 (x - 5)
y + 3 = -1/5 x + 1
y = -1/5 x + 1 - 3
y = -1/5 x -2
Answer:
Step-by-step explanation:
Slope of the ⊥ line is ( - [tex]\frac{1}{5}[/tex] )
y - ( - 3 ) = - [tex]\frac{1}{5}[/tex] ( x - 5 )
y + 3 = - [tex]\frac{1}{5}[/tex] x + 1
y = - [tex]\frac{1}{5}[/tex] x - 2
