Answer:
D
Step-by-step explanation:
Let's solve your equation step-by-step.
x2+4=3x+8
Step 1: Subtract 3x+8 from both sides.
x2+4−(3x+8)=3x+8−(3x+8)
x2−3x−4=0
Step 2: Factor left side of equation.
(x+1)(x−4)=0
Step 3: Set factors equal to 0.
x+1=0 or x−4=0
x=−1 or x=4
Answer:
x=−1 or x=4
X - 0.38x = 868......x is the same as 1x
1x - 0.38x = 868
0.62x = 868...now divide both sides by 0.62
x = 868 / 0.62
x = 1400 <==
Answer:
44y
Step-by-step explanation:
bcause they are the same you just add them normally but add the y at the end
Answer:
first option
Step-by-step explanation:
Given
(3x² + 2x - 3)(x - 1)
Each term in the second factor is multiplied by each term in the first factor, that is
3x²(x - 1) + 2x(x - 1) - 3(x - 1) ← distribute parenthesis
= 3x³ - 3x² + 2x² - 2x - 3x + 3 ← collect like terms
= 3x³ - x² - 5x + 3
Answer:
A) 3
Step-by-step explanation:
If you simply look at the given numbers, it should be pretty clear that 3 tenths is 3 times 1 tenth.
When Mary puts 1/10 kg in each cage, she can do that for 3 cages with 3/10 kg of bird seed.
__
If you let c represent the number of cages, then the amount of bird seed used will be (1/10)c. This will be equal to the amount available when we use it all for filling cages:
(1/10)c = (3/10)
Multiply both sides of the equation by 10:
c = 3
Mary can fill 3 cages with available seed.
