These are the equations:
2L+2W=58
L=W+5
Now plug in the second one in the first one:
2(W+5)+2W=58
4W+10=58
4W=48
W=12
L=17
Answer:
The angle for the top of the triangle is 79. For the right corner would be 56. Then going to the bottom of the blue triangle vertice would be 75. The missing angle next to that one would be 55/
Step-by-step explanation:
Answer:
For the time interval 0 to 2 the ball is in the air.
Select the options according to this.
Step-by-step explanation:
The equation should be 
Let's find the x intercepts to answer this question.
To find x intercept where the h(t) is 0.

Solve the equation for t.
Use quadratic formula to solve the equation.
a=-16
b=-30
c=124

Plug in the values of a, b and c into the formula

Simplify it



Simplify it to get two values for x

x can not be negative, here x represents time t.
So, it starts from 0 and remains in the air for 2 seconds.
Answer:
60
Step-by-step explanation:
Answer:
2(2x + 5)
Step-by-step explanation:
2 is common to both 4x and 10, so 4x + 10 = 2(2x + 5)
