Answer:
73
Step-by-step explanation:
(7.7 * 2) + (9.6 * 6) = 74
I think it would be false because many things have to be in a certain sequence or order. I don’t know how to explain it that well but...

Step-by-step explanation:
Answer:
398 ft²
Step-by-step explanation:
Assuming you have correctly described the total area in terms of non-overlapping triangles and a rectangle, you can put the dimensions into the appropriate area formula and add up the pieces.
Triangle area = 1/2·bh
Rectangle area = bh
___
So, the <em>first triangle</em> has an area of ...
1/2·(20 ft)(20 ft) = 200 ft²
The <em>second triangle</em> has an area of ...
1/2·(6 ft)(6 ft) = 18 ft²
The <em>rectangle</em> has an area of ...
(30 ft)(6 ft) = 180 ft²
And the area total is ...
200 ft² +18 ft² +180 ft² = 398 ft²
Answer:
(1) C
(2) C
(3) 4
(4) False
Step-by-step explanation:
(1) If DF = FB, then point F is called the midpoint and segments DF and FB are congruent.
(2) If ray FA bisects angle EFB, then angles EFA and AFB are congruent. If measure of angle EFA = 47 degrees, the measure of angle EFB = 47 degrees.
(3) If DF = x+2, FB = 2x+1 and DB = 15, then
DF + FB = DB
x+2+2x+1=15
3x+3=15
3x=15-3
3x=12
x=4
(4) If x=4, then
DF=4+2=6
FB=2·4+1=9
Since DF is not congruent to FB, F is not a midpoint. False
