Answer:
1280
Step-by-step explanation:
rewrite (-8) times (-8) as an equivalent addition problem which is 8 times 8 = 64
take 64 then times it by 20 which is 64 times 20 equals 1,280
Hope this helps:)
Answer: C) d+13/d+4
Here’s why:
Step 1: Rewrite the factor
d^2 + 7d +4d +28 / (d+4)^2 + 6 / d+4
Step 2 : factor out d from the expression and factor out 4 from the expression
d × (d+7) + 4(d+7) / (d+4) ^2 + 6 / d+4
Step 3: Factor out d+7 from the expression
(d+7) × (d+4) / (d+4) ^2 + 6 / d+4
Step 4: simply the expression
d+7 / d+4 + 6/ d+4
Step 5: write all numerators above the common denominator
d+7+6 / d+4
Step 6: add the numbers and you get
d+13 / d+4
Answer:
x = -2 or x = 1/2
Step-by-step explanation:
First get the eq in standard form, which means:
x² should not have that 2 in front of it
move the other 2 to the left
so first let's divide by 2:
x² + 3/2 x = 1
now move the 1 to the left
x² + 3/2 x - 1 = 0
now look for two numbers that, when multiplied, give -1, and when added, give 3/2. This is a bit of trial-and-error if you want to solve in this way.
The numbers are 2 and -1/2, since 2*-1/2 = -1, and 2 - 1/2 = 3/2
The factorization thus is:
x² + 3/2 x - 1 = (x+2)(x-1/2) = 0
Either factor (x+2) or (x-1/2) can be zero to solve the solution, hence x = -2 or x = 1/2
Answer:
10
Step-by-step explanation:
5C2 =<u>5!</u>
2! (3)!
=<u>1 x 2 x 3 x 4 x 5</u>
(1 x 2) (1 x 2 x 3)
=<u>4 x 5</u>
2
=<u>20</u>
2
5C2 = 10
