Answer:
x^2 + 4x + 7
Step-by-step explanation:
(2x + 6) + (x^2 + 2x + 1) Remove parentheses.
2x + 6 + x^2 + 2x + 1 Combine like terms and reorder.
x^2 + 4x + 7
Hope this helped!
Answer:
G
Step-by-step explanation:
vertex formula = a(x-h)^2 + k
vertex is (h, k) so (-1, -4) means
y = a(x+1)^2-4
passes through (1, 8) so when x = 1 and y = 8
8 = a(1+1)^2-4 = 4a - 4
4a = 4
a = 1
Answer:
x >= 0 & y<0
x >= 0 means that x is non-negative
y<0 means that y is negative
An equilateral triangle is a triangle where all sides are of equal lengths. So, the angles are of equal values as well which is 60. We use the angle and the height of the triangle to determine the side length. We do as follows:
tan (60) = 15 / base/2
base = 10√3 = side length
