Answer:
Collage = Bad lol
Step-by-step explanation:
I agree with what that person told you. The expression -2(x+10) is equivalent to -2x-20
Multiply the outer -2 with the inner x to get -2 times x = -2x
Multiply the outer -2 with the inner term 10 to get -2 times 10 = -20
So overall, -2(x+10) = -2x-20
--------------------------------------------
So that's how we're able to go from this

to this

The only thing that changes is the left side. The inequality sign will not flip. It only flips if we multiply both sides by a negative number.
Standard: x=4
implicit: x-4=0
Answer:
A- l-0.13l
Step-by-step explanation:
l-0.14l is the same as 0.14
l0.13l is the same as 0.13
l-0.18l is the same as 0.18
l-0.2l is the same as 0.2
l14l is the same as 14
The only value that is less that 0.14 is 0.13, making A the correct answer.
Answer:
She needs 50 ft² of wood to cover the table
Step-by-step explanation:
You need to know the formula for area of a trapezoid, which is
A = (B1 + B2)h/s (add the bases together, multiply by the height, then divide
by 2)
We are given B1 = 12, B2 = 8, and h = 5, so plug them in and simplify
A = (12 + 8)(5)/2
A = (20)(5)/2
A = 100/2
A = 50 ft²
