Answer: (7 + d) 4 and 4 (7 + d)
Step-by-step explanation:
<em>4 (d + 7) = 4d + 28</em>
<em />
(7 + d) 4 = 28 + 4d (flipped version of 4d + 28)
4 (7 + d) = 28 + 4d (the same)
Answer:
27.2 ft
Step-by-step explanation:
Let's set up a ratio that represents the problem:
Object's Height (ft) : Shadow (ft)
Substitute with the dimensions of the 34 foot pole and its 30 foot shadow.
34 : 30
Find the unit rate:
The unit rate is when one number in a ratio is 1.
Let's make the Shadow equal to one by dividing by 30 on both sides.
Object's Height (ft) : Shadow (ft)
34 : 30
/30 /30
1.13 : 1
Now, let's multiply by 24 on both sides to find the height of the tree.
Multiply:
Object's Height (ft) : Shadow (ft)
1.13 : 1
x24 x24
27.2 : 24
Therefore, the tree is 27.2 feet tall.
Answer:
(2,8)
Step-by-step explanation:
G=3
If you multiply out x+7 and x-4 you get <span>x^2+3x-28
The 3 in the above equation is like the G</span>
Answer: 6
A coefficient is a numerical or constant quantity placed before and multiplying the variable in an algebraic expression.
In this case we want to find the coefficient that has x. 6 is the only coefficient in the expression 6x + 9y + 15z that has the coefficient of x.
Basically, a coefficient is simply a number that has a variable after it.
