B. x2 – 4x + 3 = (x – 3)(x – 1)
Answer:
90°, 78°, 12°
Step-by-step explanation:
let the third angle be x then the second angle is 7x - 6
Since 1 of the angles in the triangle is 90° then the second and third angles sum to 90° , then
x + 7x - 6 = 90
8x - 6 = 90 ( add 6 to both sides )
8x = 96 ( divide both sides by 8 )
x = 12
Then
second angle = 7x - 6 = 7(12) - 6 = 84 - 6 = 78°
The 3 angles are 90°, 78°, 12°
<u>Equate mom's percentage to quantity:</u>

<u>Find 1%</u>
1% = 80 ÷ 40 = 2
-
<u>Find 100% (Total):</u>
100% = 2 x 100 = 200

Answer; There are 200 CDs in the store for sale.
321517 milileters and there you go
Denali- 6.7x70= 469
The building should be strong enough to withstand an earthquake of that magnitude.
Rat Island- 7.8x30=234
The building should be string enough to withstand an earthquake of that magnitude.
Hope this helps! ;)
