Answer:
x=2.5
Step-by-step explanation:
the first thing you want to do is simplify like terms.
you could say this is as 4(x+7)=38
this can easily be solved algebraically.
first use distributive property on the four
this leaves you with 4x+28=38
next, subtract 28 from both sides
4x=10
now divide everything by four and you get x=2.5
Answer:
Step-by-step explanation:
Let L represent the length of the triangle.
Let W represent the width of the triangle.
The length of a rectangle is four more than three times the width. This means that
L = 3W + 4
The formula for determining the perimeter of a rectangle is expressed as
Perimeter = 2(L + W)
If the perimeter of this rectangle is at least 70 square centimeters, an inequality that can be solved to find the width of the rectangle is
2(L + W) ≥ 70
L + W ≥ 70/2
L + W ≥ 35

Answer:
Answer:
h = \frac{2A}{b}
Step-by-step explanation:
Given
A = \frac{1}{2} bh
Multiply both sides by 2 to clear the fraction
2A = bh ( isolate h by dividing both sides by b )
h = \frac{2A}{b}
