Answer:
= (x+4) (x-7)
Step-by-step explanation:
x²-3x -28
Product = -28
Sum = -3
numbers = -7 and 4
Thus;
x²- 3x -28 ; replacing -3x with -7x and 4x
x²-7x +4x -28
x(x-7) + 4(x-7)
<u>= (x+4) (x-7) </u>
Answer:
-8*2x would be -16x and -8*-8=64 so the ansewer would be _16x+64

Which number is the best estimate of 866,214,000,000 using powers of 10
a) 9 × 10¹¹
b) 8 × 10¹¹
c) 10 × 11¹⁰
d) 8 × 10-¹¹
Answer:
a) 9 × 10¹¹
Step-by-step explanation:
When we want to estimate a number using the power of 10, we are trying to write the number in a standard form.
We are to estimate :866,214,000,000 using powers of 10
Hence,
8.66214000000 × 10¹¹
We round up to the nearest whole number
= 9 × 10¹¹
Therefore, the best estimate for 866,214,000,000 using powers of 10
= 9 × 10¹¹
3(0) + 3 = 3
3(1) + 3 = 6
3(2) + 3 = 9
3(3) + 3 = 12
3(4)+3 = 15
Solve 3x+3 = 3
Subtract 3 from both sides so you get
3x = 0
X= 0
