Answer:
vertex = (- 7, - 87)
Step-by-step explanation:
given a parabola in standard form : ax² + bx + c : a ≠ 0
Then the x- coordinate of the vertex is
= - 
p² + 14p - 38 is in standard form
with a = 1, b = 14, c = - 38, hence
= - 
= -7
substitute x = - 7 into the equation for corresponding value of y
y = (- 7)² + 14(- 7) - 38 = 49 - 98 - 38 - - 87
vertex = (- 7, - 87)
So, the base is 20 and you will multiply the base by the height which is 15 so if you want it with the triangles and squares then, you break down the parallelogram into 2 triangles and 1 square you will get the height of the 2 triangles and the square and add them all up and you should get 300 if you need me to explain better i will!
Answer:
Step-by-step explanation:
Find the area of each shape (rectangle and triangle) and then add the areas together.
Area of rectangle:
A = bh
A = 14*12 = 168 cm2
Area of triangle:
A = 1/2*bh
A = 1/2(16)(21 - 12)
A = 1/2(16)(9)
A = 1/2(144)
A = 72 cm2
Add areas together: (area of the whole shape)
168 + 72 = 240 cm2
Answer: 15
Step-by-step explanation: To evaluate an expression, we plug the value of the variable into the expression and simplify.
Since we have 7 - 2x and x is -4, we have 7 - 2(-4).
Simplifying from here, 2(-4) is -8 so we have 7 - (-8).
Now, remember that a a minus sign followed by a
negative sign turns the two signs into a plus sign.
So 7 - (-8) can be thought of as 7 + (+8) which is 15.
10.2=10.20
So, 10.2 is bigger than 10.02
