How many terms are in the algebraic expression -7+12x^4-5y^8+x? 1 2 3 4

4

Step-by-step explanation:

-7+12x^4-5y^8+x

Terms:

1: -7

2: 12x^4

3: 5y^8

4: x

These are all different terms so there are 4

x = 10.1

step-by-step explanation:

all of the angles of a tirangle add up to 180º

180 - 65 = 115 (since we already know the value of one angle)

(2x + 7) + (8x + 7) = 115

(combins like terms) 10x + 14 = 115

(isolate the variable subtract 14 from both sides): 10x = 101

(find the variable divide both sides by 10): x = 101/10

x = 10.1
