(2x-6)(3x-5)

multiply the two brackets together

(2x)(3x)=6x^2

(2x)(-5)=-10x

(-6)(3x)=1-8x

(-6)(-5)=30

6x^2-10x-18x+30

Answer:

6x^2-28x+30

andre [41]
The answer is 12.8 cm³

<span>The volume ( v) of a gas in a container at a constant temperature varies inversely as the pressure (p):
v = k/p
p * v = k  (k - constant)

p1v1 = k
p2v2 = k
So, p1v1 = p2v2

v1 = 24 cm</span>³
p1 = 16 lb
v2 = ?
p2 = 30 lb

24 * 16 = x * 30
384 = x * 30
x = 384 / 30
x = 12.8 cm³

1. the factors of 24 are 1, 24, 2, 12, 3, 8, 4, and 6. Each pair, fx. 1 and 24 with be 24 when multiplied. 2. Quaderant 3, quaderants go from 1 to 4 counterclockwise, and a (negative x, negative y ), will be in the 3rd quaderant if you go counterclockwise. 3. 7×x, the answer is simple 7 and x, with the key words "product of" which signify multiplication so it will be 7 times x.

Can someone help me
marshall27 [118]

Answer:

16682.7 cm³

Step-by-step explanation:

The total volume is the volume of the cone plus half the volume of a sphere:

V = ⅓ π r² h + ½ (4/3 π r³)

V = ⅓ π r² h + ⅔ π r³

V = ⅓ π r² (h + 2r)

Given that r = 4.15 cm and h = 10.2 cm:

V = ⅓ π (4.15)² (10.2 + 2×4.15)

V ≈ 333.65

The volume needed for 50 cones is therefore:

50V ≈ 16682.7 cm³

Ed Moura has $32000 invested in stocks paying 6% .how much additional money should he invest in certificates of deposit paying 3
inna [77]

Answer:

Ed Moura invest $64000 in certificates of deposit paying 3%

Step-by-step explanation:

Ed Moura has $32000 invested in stocks paying 6%.  

Additional money in certificates of deposit paying 3% =x  

so that the average return on the two investments is 4%.  

32000*6% +3%*x = 4%(32000+x)

32000*0.06 +0.03*x = 0.04(32000+ x)

1920 + 0.03x = 1280 +0 .04x

1920 - 1280 = 0.04x - 0.03x

0.01x = 640

x = 64000

x = $64000

x= $64000 in certificates of deposit paying 3%

Thank you.
