Answer:
14
Step-by-step explanation:
280 divided by 20 is 14 when you divide by those 2 numbers you get how much they would cost. also 14x20 is 280
Answer:
b-4/5b
Step-by-step explanation:
b is decreased by 80%
dat is 80/100×b
= b-80/100b
b-4/5b
Answer:
C. (x + 4)(x + 5).
Step-by-step explanation:
We need 2 numbers whose product is + 20 and whose sum is + 9.
They are + 5 and + 4 , so
x2 + 9x +20
= (x + 4)(x + 5).
Answer:
36
Step-by-step explanation:
X equals 12, substitute X for 12
3(12)=36
Answer/Step-by-sep explanation:
1. Given:
∆NMK ≅ ∆TRP




a. To complete the congruent statement, thus: ∆MNK ≅ ∆RTP
b. The side that is congruent to
is
. Thus:
≅ 
c. Since
≅
, therefore:

(substitution)
Add 1 to both sides


Divide both sides by 3


2. a. Slope of LK = 
Slope of LM = 
b. ✍️Length of LK is the distance between L(-7, 4) and (-4, 8):






✍️Length of LM is the distance between L(-7, 4) and (-2, 1):





(nearest tenth)
∆KLM is not an isosceles ∆ because it does not has two equal side lengths. This we can see because LK and LM are not equal.
Therefore, Anthony is incorrect. Am isosceles ∆ has two equal sides.
