Answer:
=(x-3)(x+7)
Step-by-step explanation:
To factor the trimonial: , we follow these steps:
Step 1: Multiply the first and last term
Step 2: List out product factors of the term derived above
Step 3: Determine which of the factors sum up to the middle term 4x
The required product is: -3 and 7
Therefore: -3x+7x=4x
Step 4: Replace the middle term by the expression derived in step 3 and factorize.
Answer:
B(2,4)
Step-by-step explanation:
A(-1,-9)
M(0.5,-2.5)
with M we can find x₂ and y₂
x = 0.5
x = x₁+x₂/2
0.5 = (-1 + x₂)/2
(x₂ -1)/2 = 0.5
x₂-1=0.5×2
x₂-1=1
x₂=2
for y₂
y= -2.5
y=(y₁+y₂)/2
y=(-9+y₂)/2
-2.5=(-9+y₂)/2
-9+y₂=-2.5×2
-9+y₂=-5
y₂=-5+9
y₂=4
.: coordinates are B(2,4).

Answer: Theo bought a pair of shoe for 36$
Step-by-step explanation:
25% = 0.25
