Area=84 m^2
area of the triangle= 1/2*4*7=14
the area of the other triangle is also 14.
area of rectangle=8*7=56
56+14+14=84 m^2
It’s A thinks for the time
B. The equation can become −2(4x − 1) = 12 by applying the addition property of equality because we have: <span>−2(4x − 1) − 7 = 5 / + 7 <=> -2(4x-1) = 12;</span>
Answer:
<em>Result: 23</em>
Step-by-step explanation:
<u>Evaluating Algebraic Expressions</u>
Given an expression where variables (letters) are included, evaluate the expression at specific values of the variables means to substitute the values into the expression, operate, and give the final result.
The expression provided in the question is:
4m + 3
Evaluate at m=5
Substitute m for 5 recalling 4m really means 4*m, a product:
4*5 + 3 = 20 + 3 =23
