Answer: x=7
Step-by-step explanation:
Since AB is a bisector, it cuts the angle in half, and since we know that the angle is a right angle, we know it’s 90 degrees, so knowing that you use the equation 7x-4= 45 (since 45 is half of 90), add 4 to both sides so you have 7x=49, the divide 49 by 7 and you get 7, so x= 7

D. -4/3
Let's solve your equation step-by-step.
9x2+24x+20=4
Step 1: Subtract 4 from both sides.
9x2+24x+20−4=4−4
9x2+24x+16=0
Step 2: Factor left side of equation.
(3x+4)(3x+4)=0
Step 3: Set factors equal to 0.
3x+4=0 or 3x+4=0
x=
−4
/3

Answer:
D. 8
Step-by-step explanation:
We need to count how many are longer than 7. There are 4 leaves that are 7 inches long. 3 are 8 inches long. 1 in 9 inches long. Adding these up gives us our answer. Let x be the leaves 7 inches or longer.

4+4=x
Add 4 and 4
8=x
There are 8 leaves that are 7 inches or longer.
