Hello from MrBillDoesMath!
Answer:
x = 50
Discussion:
(4x +5) ( 2x - 2) = 8x^2 - 8x + 10x - 10
= 8x^2 + 2x - 10 (A)
(16x^8)/(2x^6) + 90 = 8x^2 + 90 (B)
Setting (A) = (B) gives
8x^2 + 2x - 10 = 8x^2 + 90
Subtract 8x^2 from both sides:
2x - 10 = 90
Add 10 to both sides:
2x = 90 + 10 = 100
Divide both sides by 2:
x = 100/2 = 50
Thank you,
MrB
Answer:
4/663
Step-by-step explanation:
1/13 = probability of ace (as 1st card)
4/51 = probability of jack (as 2nd card) -->
4/663
The base length is 5.5 cm.
Explanation:
Area of triangle = base x height x 1/2
Let b cm be the base length of the triangular flag.
22 = b x 8 x 1/2
22 x 2 ÷ 8 = b
b = 44 ÷ 8
b = 5.5
Answer:
B. 17.8
Step-by-step explanation:
c^2 = 14^2 + 11^2 (Pythagoras theorem)
c^2 = 196 + 121
c^2 = 317
c = √317
c = 17.8
