Yes there will be more than one
Answer: I’m going to do the first problem with a fully detailed explanation and just answer the other ones! :)
Factoring: v^2-4v-60
The middle number is -4 and the last number is -60.
Factoring means we want something like
(v+_)(v+_)
Which numbers go in the blanks?
We need two numbers that...
Add together to get -4
Multiply together to get -60
Can you think of the two numbers?
Try 6 and -10:
6+-10 = -4
6*-10 = -60
Fill in the blanks in
(v+_)(v+_)
with 6 and -10 to get...
(v+6)(v-10)
Second Problem: (x-4)(x-9)
Third Problem: 6(x+5)(x+8)
Fourth Problem: (k+5)(k+10)
Fifth Problem: (a-4)(a-4)
Answer:
n=-12
Step-by-step explanation:
2-3(n+4)=26
Distribute:
2-3n-12=26
add 10 to both sides:
-10-3n=26
divide by -3 on both sides:
-3n=36
Answer:
n=-12
Answer:
Scale factor of 1.6.
Step-by-step explanation:
The triangle is dilated and the images is an enlargement of the pre-image. This means all angles of the triangles are congruent and these form similar triangles. Because they are similar triangles which have been dilated, they have a common ratio known as the scale factor between their side lengths. The scale factor here is 1.6 and can be found by using the ratio 0.8/0.5 = 1.6.
Answer:
<A = 56degrees
<B = 34degrees
<C = 56degrees
Step-by-step explanation:
From tyhe diagram, the sum of m<C and m<D is 180degrees. Hence;
<C + <D = 180
<C + 124 = 180
<C = 180 - 124
<C = 56degrees
Also;
<B + 90 + <C = 180
<B + 90 + 56 = 180
<B + 146 = 180
<B = 180 - 146
<B = 34degrees
Similarly;
<A + <B = 90
<A + 34 = 90
<A = 90 - 34
<A = 56degrees
