Answer:
1) (x+4)2 =49
Step-by-step explanation:
x^2+8x-33 = 0 Factor this equation
(x + 11)(x - 3) = 0 Set each equation equal to 0
x = -11 and 3
Test the first equation to see if it has the same solution
(x+4)2 = 49 Simplify the parentheses
(x+4)(x+4) = 49 FOIL the equation
x^2 + 8x + 16 = 49 Subtract 49 from both sides
x^2 + 8x - 33 = 0 This is the correct solution.
Answer:
It is one-half the area of a rectangle with sides 2 units × 3 units.
Step-by-step explanation:
we have the coordinates of triangle ABC
A(4,5),B(5,2),C(3,2)
Plot the coordinates of triangle to better understand the problem
see the attached figure
step 1
Find the area of triangle ABC
The triangle ABC is an isosceles triangle `(AB=AC)
The area of triangle ABC is
we have
---> difference of the x-coordinates
---> difference of the y-coordinates
substitute
step 2
Find one-half the area of a rectangle with sides 2 units × 3 units
therefore
The area of triangle ABC is one-half the area of a rectangle with sides 2 units × 3 units
Answer:
14x - 2
Step-by-step explanation:
([7x] { -1}) ([7x] {- 1})
Add together
0.37 inches on each necklace or 37/100.
You just need to do 1.48 divided by 4.
