Answer:
58.9 m
Step-by-step explanation:
To find the width, use the area by dividing 215.2/16 to get 13.45. You now have the length and the width so add 16 + 16 + 13.45 + 13.45. You get 58.9.
Hope it helps!

12) Jennifer earns $78 per day working at a supermarket. She spends $8 each day at lunch and her gas to get to and from work is $6 per day. How much money will she earn in 28 days?
Answer:
$1792
Step-by-step explanation:
$78 x 28 = 2184
28 x $8 = 224
28 x $6 = 168
168 + 224 = 392
2184 - 392 = $1792
Check Work:
1792 + 392 = 2184

Answer:
(7x+2)(3x-1); (5x+4)^2 or (5x+4)(5x+4);
Step-by-step explanation:
formula to find area is L* W = A ; meaning length multiplied by width equals to the area.
21.
using the formula to find area...
l*w=a
(7x+2)(3x-1) would be your answer
btw, don't put the "=a" at the end, since it's an expression :))
22.
since the problem states that it's a square, you can just say either...
(5x+4)^2 or (5x+4)(5x+4) not sure which one your teacher accepts

Answer:
A. <dilation by a factor of 1/7>
Step-by-step explanation:
Rotation, reflection, and translation are "rigid" motions that preserve congruence.
Dilation does not preserve congruence. Dilation multiplies the coordinates by a dilation factor, as in the transformation of choice A.
(x, y) ⇒ (x/7, y/7) . . . does NOT preserve congruence

Determine the measures of the unknown angles in the figure.
m < APD =
m < CPE =
m < BPD =
Answer:
angle APD=115 degrees
angle CPE=25 degrees
angle BPD=65 degrees
Step-by-step explanation:
APD=180-65=115 because it is supplementary
CPE=90-65=25 because it is complementary
BPD=65 because it is an alternate angle
The measurements of the asked angles are m ∠APD = 115°, m ∠CPE = 25° and m ∠BPD = 65°.
What is an angle?An angle is a geometrical shape that is formed by two rays or lines, called the sides or arms of the angle, that share a common endpoint, called the vertex of the angle.
Given is a figure, we need to find the measurement of the asked angles,
m ∠APD, m ∠CPE and m ∠BPD.
So,
∠APD + ∠APC = 180° [linear pair]
∠APD = 180° - 65°
∠APD = 115°
∠CPE + ∠CPA = 90° [complimentary angles]
∠CPE = 90° - ∠CPA
∠CPE = 90° - 65°
∠CPE = 25°
∠BPD = ∠APC [vertical angles]
∠BPD = 65°
Hence, the measurements of the asked angles are m ∠APD = 115°, m ∠CPE = 25° and m ∠BPD = 65°.
