Answer:
2x + 8
Step-by-step explanation:
solve by using the distributive property
2(x + 4) = (2)(x) + (2)(4)
2x + 8
Answer:
small boxes= 15
large boxes = 5
Step-by-step explanation:
let the number of large boxes be denoted as
Then the number of small boxes is 3 time that of large boxes, i.e.
If the total volume of all boxes is 235 cubic feet,
Then, we can form the following relationship (equation)
17*x+10*(3x)=235
x=5
Therefore the number of large boxes is 5
and that of small boxes is
3*5=15
I hoped i helped
The answer is 15+99x
______
x+10
Answer:
D. 340 square inches
Step-by-step explanation:
Side length translates to 1 side of the square, so you do 10 x 10 to find the area of the square.
10 x 10 = 100
The triangle one isn't much more difficult. The formula for finding the area of a triangle is bh1/2
So:
10 x 12 = 120/2=60
From there just multiply the result by 4- the amount of triangles on the square pyramid, and you'll get your answer.
60
x 4
240 + 100 = 340 square inches
if this helped brainliest would be epic
Answer:
The first graph is the graph of the solution set of the inequality 
x ≥ 9
Step-by-step explanation:
If multiply or divide the two sides of the inequality by a negative number, then we must reverse the sign of the inequality
Example:
2 < 3, when we divide both sides by -1, then it will be -2 > -3
<em>Let us solve the question</em>
∵ x ≥ 9
→ To find x divide both sides by
∵ is a negative number
→ From the rule above
∴ Reverse the sign of inequality
∴ x ≤ -15
∵ We have an equal sign with the sign of inequality
∴ The vertex of the arrow should be bold
∵ The sign of inequality is smaller than
∴ The arrow must be pointed to the left ⇒ (negative direction)
∵ x ≤ -15
∴ The arrow represents it has a bold starting point at -15 and pointed
to the left
∴ The answer is the first graph
