Answer:
Below.
Step-by-step explanation:
If we let the two numbers be x and y we could have the following equations:
xy = 112
y = 3x + 4.
Then if we want to find the value of x, from the first equation we get
y = 112/x, which we substitute in the second equation;
112/x = 3x + 4.
all you have to do is divide 5026 by 628 which gives you 8.003 or 8 as the final answer.
8
Which one the on number 1 ?
Answer:
• 72 ft²
Step-by-step explanation:
The bottom side length of the triangle is the difference between the top base length and the bottom base length:
13 ft - 5 ft = 8 ft
The vertical side length of the triangle is the same, because the triangle is an isosceles right triangle.
Since we know the base lengths and height of the trapezoid, we can use the usual formula for the area:
A = (1/2)(b1 +b2)h
= (1/2)(5 ft + 13 ft)(8 ft) = 72 ft²
