Answer:
Step-by-step explanation:
we know that
Applying the <u>Intersecting Secants Theorem</u>
Solve for x
Activity 3
1) 2m^2(4m^2 + 3m + 2)
2) (x + 4)^2 (x - 4)
3) (x + 9)(x - 7)
4) 5y(17y - 4z)
5) (2x - y)(6x + 5y)
Activity 4
1) 80 units because when you sub h = 9, you get 400 as the answer and because it’s a square, you square root 400 which is 20 units per side.
2) x = 7cm because when you multiply (x + 5)(x - 3), you get x^2 + 2x - 15 = 48 and when you solve it you get x is equal to 7, -9, because the length of the rectangle is positive x is equal to 7.
3) the binomial would be (9x + 1)^2.
Answer:
8.3
Step-by-step explanation:
<u>do whats in the brackets first.</u>
13-17-1.3= -5.3
<u>rewrite the equation</u>
3-7+2-[-5.3]+5
3-7+2= -2
<u>rewrite the equation</u>
-2-[-5.3]+5
when 2 negative signs are together u change it to a positive sign.
<u>rewrite the equation</u>
-2+5.3+5
-2+5.3= 3.3
<u>rewrite the equation</u>
3.3+5=8.3

The answer is that Max has 45 red cards.
How:
40/x = 8/9
Then cross multiply
360= 8x
X= 45
