Answer:

Step-by-step explanation:
We can solve for this equation by isolating
on one side. To do this, we can "reverse" the equation.

Let's divide both sides by 3.

Add 3 to both sides:

Multiply both sides by two (since
)

According to the question,
6x + 90 = -42
<h3>To Find:</h3>
The value of x.
<h3>Solution:</h3>
6x = -42 + 90
or, x = 48/6
or, x = 8
<h2>Answer:</h2>
The value of x is 8.
2L + 2w = 112 ---> L + w = 56 ---> w = 56- L
Area = L*w = L(56-L) = 735
56L - L^2 = 735
0 = L^2 - 56L + 735
0 = (L - 21)(L - 35)
THe dimensions of the rectangle are 35 x 21
Answer:
a. 16
Step-by-step explanation:
area of a triangle=1/2(bh). In this case, b=10 and h=3 1/5
multiply 10 and 3 1/5 to get 32
multiply 32 by 1/2 to get 16.
