For each quantity, decide whether circumference or area would be needed to calculate it. 1. The distance around a circular garden
2. The amount of fabric needed to make a circular tablecloth
3. The equator of the Earth
4. The amount of cheese it takes to cover a circular pizza

step-by-step explanation:

inverse operation of addition

2 over 5 and 4 over 15

don’t know last one sorry

step-by-step explanation:

"standard form:

3x2 + 14x − 10 = 0

solutions based on quadratic formula:

x1   = −14 − √ 142 − 4×3×(−10) /   2×3   = −14 − 2 × √ 79 /   6   ≈ −5.296

x2   = −14 + √ 142 − 4×3×(−10) /   2×3   = −14 + 2 × √ 79 /   6   ≈ 0.629
