Answer:

Part A: 48in^2

Part B: 4in by 12in, 8in by 6in, and 3in by 16in

Step-by-step explanation:

Volume/height is the area of the base:

480/10 = 48in^2

Any two numbers that multiply to 48 are possible dimensions of the block:

4*12, 8*6, 3*16

-4 (2x + 13) + 3x = 80<br> How do you solve this out and get the answer
shusha [124]
Hey :)

x= -12

Use the distributive property to multiply −4 by 2x+13


−8x−52=3x+80
Subtract 3x from both sides
−8x−52−3x=80


Combine −8x and −3x to get −11x
−11x−52=80

Add 52 to both sides
−11x=80+52


Add 80 and 52 to get 132
−11x=132


Divide both sides by −11
x= 132/-11
​

Divide 132 by −11 to get −12
x=−12


Hope this helps :)

Let f(x) = x + 7 and g(x) = x − 4. Find f(x) ⋅ g(x). (1 point) x2 − 3x −28 x2 − 3x − 11 x2 + 3x − 28 x2 + 3x − 11
slavikrds [6]

f(x)=x+7\\g(x)=x-4\\f(x)*g(x)=(x+7)(x-4)\\f(x)*g(x)=x^2+3x-28

So it's x^2+3x-28

Which graph represents the solution set for the quadratic inequality x2 + 2x + 1 &gt; 0
AnnyKZ [126]

we have

x^{2}+2x + 1 > 0

we know that

x^{2}+2x+1=(x+1)^{2}

so

(x+1)^{2}> 0

two solutions

<u>first solution </u>

(x+1)> 0

x > -1

the first solution is the interval---------> (-1,∞)

<u>second solution</u>

-(x+1)> 0

-x-1> 0

-x> 1

x< -1

the second solution is the interval---------> (-∞,-1)

therefore

the solution is all real numbers except the number -1

the answer in the attached figure
