C
Multiple a and c so 2x6=12
Find the factors of twelve that add to equal 7
The factors are four and three
Put them in parenthesis with a in front of x so
(2x+3)(2x+4)
Four can be divided by two so it turns into
(2x+3)(x+2)
Answers:
Scale factor is 8:5
Area ratio is 64:25
Volume ratio is 512:125
=================================================
Explanation:
Divide the second surface area (375) over the first surface area (960) to get
375/960 = 0.390625
Then take the square root of this to get
sqrt(0.390625) = 0.625
The decimal value 0.625 converts to the fraction 5/8, which turns into the scale factor 8:5
-----------------
Once you know the scale factor, you can square both sides to get the area ratio
8:5
8^2:5^2
64:25
The area ratio is 64:25
Then go back to the scale factor, and cube each part to get the volume ratio
8:5
8^3:5^3
512:125
The volume ratio is 512:125
Circumference of a circle = 2π r
2*3.14*13 = 81.64 = 81.6
The <u>congruency theorem</u> gives you an opportunity to prove that <u>two triangles</u> are <u>congruent</u>.
Consider triangles WUT and VTU. In these triangles:
- WU≅VT (given);
- ∠T≅∠U, m∠T=m∠U=90° (from the diagram);
- side TU is common.
Note that triangles WUT and VTU are right triangles, because m∠T=m∠U=90°. Side TU is common leg and sides WU and VT are hypotenuses.
HL theorem states: if the hypotenuse (WU) and one leg (TU) of a right triangle (ΔWUT) are congruent to the hypotenuse (VT) and one leg (TU) of another right triangle (ΔVTU), then the triangles are congruent.
Answer: correct choice is B
