Answer:
select -3 and 2
Step-by-step explanation:
f(x)=g(x) means set them equal and solve for x
x^2+2x-8=-x^2+4
Add x^2 on both sides and subtract 4 on both sides.
2x^2+2x-12=0
Divide both sides by 2
x^2+x-6=0
Think of two numbers that multiply to be -6 and add up to be 1
that is 3 and -2
so The factored form is (x+3)(x-2)=0
So x=-3 or x=2

sorry I don't know about it
Answer:
c) 325
Step-by-step explanation:
The fraction of students that went to the movies is 14/112. To find the number of students who went to the movies from a larger group, you have to find a fraction equal to 14/112, whose denominator is 2600 (the number of students from the larger group).
14/112 = x/2600
You can do cross multiplication here. Cross multiplication is multiplying the denominator of one fraction by the numerator of the fraction equivalent to it. That product will be equal to the numerator of the first fraction * denominator of the second fraction.
112*x = 14*2600
x = 325
Approximately 325 students out of 2600 students would've gone to the movie last weekend.
Answer:
<h2>b) 50in, 48in, 14in</h2>
Step-by-step explanation:
If <em>a ≤ b < c</em><em> </em>form of a right side, then <em>a² + b² = c²</em>
a) 3ft, 6ft, 5ft
3² + 5² = 6²
9 + 25 = 36
34 = 36 <em>FALSE</em>
b) 50in, 48in, 14in
14² + 48² = 50²
196 + 2304 = 2500
2500 = 2500 <em>CORRECT :)</em>
c) 53m, 48m, 24m
24² + 48² = 53²
576 + 2304 = 2809
2880 = 2809 <em>FALSE</em>
d) 8cm, 17cm, 14cm
8² + 14² = 17²
64 + 196 = 289
260 = 289 <em>FALSE</em>
