Answer:
x = 7, x = 2
Step-by-step explanation:
Given
x² = 9x - 14 ( subtract 9x - 14 from both sides )
x² - 9x + 14 = 0 ← in standard form
(x - 7)(x - 2) = 0 ← in factored form
Equate each factor to zero and splve for x
x - 7 = 0 ⇒ x = 7
x - 2 = 0 ⇒ x = 2
Answer: C.
Step-by-step explanation:
If the figure gets rotated 270ᴼ, then all of the transformed sides are perpendicular to the sides of the original figure.
The slope of DE is 2/4 (2 units up, 4 units over) or 1/2. If D’E’ is perpendicular to DE, then the slopes have negative reciprocals.
DE’s slope: 1/2
D’E’ slope: -2/1 or -2 (down 2, over 1)
Answer:
volume from geometri always:
base area × h
if have peak point always:
1/3 × base area × h
the base of the pyramid in the figure is rectangle. then base from rect. is:
l × w
= 9 × 7
= 63
let get into formula: (use the second formula because pyramid has a peak point)
=1/3 × ba × h
=1/3 × 63 × 7
=21 × 7
=147 yd³
