Answer:
B. 8sqrt(2)
Step-by-step explanation:
The legs of an isosceles right triangle are congruent and measure 45 deg. The right angle measures 90 deg. The ratio of the lengths of the sides of a 45-45-90 deg triangle is 1 : 1 : sqrt(2).
Since the hypotenuse measures 8, then the legs measure 8/sqrt(2)
8/sqrt(2) * sqrt(2)/sqrt(2) = 8sqrt(2)/2 = 4sqrt(2)
Answer: B. 8sqrt(2)
= 2x + 11
Steps
(8x+9) -(6x-2)
Remove ( a ) = a
8x + 9 - 6x + 2
Simplify
8x+ 9 - 6x + 2: 2x + 11
= 2x + 11 <----- your answer
Please tell me if this was right
The answer to this is 11.4
Answer:
(-3, 4)
Step-by-step explanation:
y = -x² − 4x + 1
y − 2x = 10
Solve the system of equations using substitution or elimination. Using substitution:
(-x² − 4x + 1) − 2x = 10
-x² − 6x + 1 = 10
-x² − 6x − 9 = 0
x² + 6x + 9 = 0
(x + 3)² = 0
x + 3 = 0
x = -3
y = 4
The solution is (-3, 4).
