Answer:
7x+4
Step-by-step explanation:
Distribute:
=(3)(4x)+(3)(−2)+−5x+10
=12x+−6+−5x+10
Combine Like Terms:
=12x+−6+−5x+10
=(12x+−5x)+(−6+10)
=7x+4
Answer:
For the box that you did not fill out the area of that shape is 190 sq units
Step-by-step explanation:
10 x 5 = 50 ÷ 2 = 25
10 x 15 = 150
10 x 3 = 30 ÷ 2 = 15
25 + 150 + 15 = 190
To find a volume of a cylinder we use the following formula:
Plug in the values:
Take the square:
Multiply the numbers:
Answer:
solution is (- 3, 5 )
Step-by-step explanation:
given the 2 equations
6x - y = - 23 → (1)
8x + 3y = - 9 → (2)
rearrange (1) expressing y in terms of x
y = 6x + 23 → (3)
Substitute y = 6x + 23 into (2)
8x + 3(6x + 23 ) = - 9
8x + 18x + 69 = - 9
26x + 69 = - 9 ( subtract 69 from both sides )
26x = - 78 ( divide both sides by 26 )
x = - 3
substitute x = - 3 into (3)
y = (6 × - 3 ) + 23 = - 18 + 23 = 5
solution is (- 3, 5 )
