y = -x^2 + 4x – 1
Find the value of x and the value of y.
A. x = 6, y = 12√2
B. X = 9, y = 12
C. X= 6√3, y= 12
D. X= 6√2, y = 24
Answer:
C.
Step-by-step explanation:
x is bisecting the baseline (cutting it in 2 halves of 6).
the third angle in the main overall triangle is 60 degrees.
remember, all angles in a triangle always add up to 180 degrees.
so, 180 - 60 - 60 = 60.
that means that all 3 angles are of equal size (60). and that means that all 3 sides must have the same length.
=> y = 12
and now using Pythagoras to calculate the height (x) of the triangle :
y² = x² + 6² (remember, this side is only half the baseline)
12² = x² + 6²
144 = x² + 36
x² = 108
x = sqrt(108) = sqrt(36×3) = 6×sqrt(3)

the area of a square is 4x^2+12x+9. Write an expression to represent the length of the side of the square.
Answer:
An expression to represent the length of the side of the square with an area of 4x^2+12x+9 in terms of x is 2x + 3
Step-by-step explanation:
all sides of a square are equal in length.
area of a square is the side length squared.
area a, side s, variable x.
a = 4x^2 + 12x + 9. s = ? x = ?
a = s^2.
a = 4x^2 + 12x + 9.
4x^2 + 12x + 9 = s^2.
x^2 + 3x + 9/4 = (s^2)/4.
factor x^2 + 3x + 9/4 = (s^2)/4.
(x + 3/2)(x + 3/2) = (s^2)/4.
(x + 3/2)^2 = (s^2)/4.
√((x + 3/2)^2) = √((s^2)/4).
take positive root.
x + 3/2 = s/2
solve for side s.
s/2 = x + 3/2
s = 2x + 3

I NEED HELP ASAP! What is the area of the following right triangle? 13 5
Answer:
Hello! answer: 30
Step-by-step explanation:
Triangle area can be found be doing base × height × 1/2 or base × height ÷ 2
So...
12 × 5 = 60 60 ÷ 2 = 30 therefore the area is 30 hope that helps!
The area of the following right-angled triangle is 30 sq units.
What is a triangle?A triangle is a three-sided closed-plane figure formed by joining three noncolinear points. Based on the side property triangles are of three types they are Equilateral triangle, Scalene triangle, and Isosceles triangle.
By the concept of Pythagoras' theorem,
13² = 5² + h².
h² = 13² - 5².
h² = 144.
h = 12.
Now, We have the height and we can find the area of the triangle,
= (1/2)×5×12.
= 30 sq units.

What is the surface area of the right rectangular prism?
Answer:
Hello! answer:
Step-by-step explanation:
6 × 12 = 72
6 × 12 = 72
3 × 12 = 36
3 × 12 = 36
3 × 6 = 18
3 × 6 = 18
72 + 72 + 36 + 36 + 18 + 18 = 252 therefore the surface area would be 252 hope that helps!
Answer:
252 in²
Step-by-step explanation:
You have to calculate the area of each surface and sum all they after:
Top area: 6 × 12 = 72 in
Front area: 3 × 12 = 36 in
Side area: 6 × 3 = 18 in
You have 2 rectangles with the same measure of the top, of the side and the front, so multiply each area per 2:
72 × 2 = 144
36 × 2 = 72
18 × 2 = 36
Now you sum all the areas:
144 + 72 + 36 = 252 in²
