Answer:
11 Square Units
Step-by-step explanation:
Let A be the area of the Rectangle
First statement: The area of the rectangle is increased by seven, we have :
A+7
Second Statement: Four less than twice the area of the rectangle
Twice the Area=2A
Four less = 2A-4
Therefore:
2A-4=A+7
Collecting like terms
2A-A =7+4
A=11
The area of the rectangle is 11 Square Units.
Answer:
y= 3x
Step-by-step explanation:
This is honestly your basic times tables if we are being honest. We know that she read 3 paragraphs per minute. We also know that in 4 minutes, she read 12 paragraphs. 4 times 3 = 12. So the answer is y=3x.
Number 6. is 34. because 67 - 34 is 33
Answer:
Step-by-step explanation:
<h3>Question 1</h3>
<u>Prove that The two triangles are congruent</u>
- ∠ABD ≅ ∠BDC - given
- BD ≅ DB - reflexive property
- ∠ADB ≅ ∠CBD - given
- ΔABD ≅ ΔCDB - ASA postulate
<u>Find the measure of angle C</u>
- ∠A ≅ ∠C - Corresponding parts of congruent triangles
- m∠C = m∠A = 180° - (62° + 70°) = 180° - 132° = 48°
<h3>Question 2</h3>
<u>Given </u>
Opposite angles are corresponding to the sides.
Therefore the angles opposite to congruent sides are also congruent:
